NAME
mpop - A POP3 client
SYNOPSIS
Mail retrieval mode (default):
mpop [option...] [--] [account...]
mpop --host=host [option...]
Configuration mode:
mpop --configure <mailaddress>
Server information mode:
mpop [option...] --serverinfo [account...]
mpop --host=host [option...] --serverinfo
DESCRIPTION
In mail retrieval mode of operation, mpop retrieves mails from one or more POP3 mailboxes, optionally
does some filtering, and delivers them through a mail delivery agent (MDA), to a maildir folder, or to an
mbox file. Mails that were successfully delivered before will not be retrieved a second time, even if
errors occur or mpop is terminated in the middle of a session.
In server information mode, mpop prints information about one or more POP3 servers.
If no account names are given on the command line, one named default will be used.
The best way to start is probably to have a look at the EXAMPLES section.
EXIT STATUS
The standard sendmail exit codes are used, as defined in sysexits.h.
OPTIONS
Options override configuration file settings, for every used account.
General Options
--version
Print version information, including information about the libraries used.
--help Print help.
-P, --pretend
Print the configuration settings that would be used, but do not take further action. An
asterisk (`*') will be printed instead of your password.
-d, --debug
Print lots of debugging information, including the whole conversation with the server. Be
careful with this option: the (potentially dangerous) output will not be sanitized, and
your password may get printed in an easily decodable format!
This option implies --half-quiet, because the progress output would interfere with the
debugging output.
Changing the mode of operation
--configure=mailaddress
Generate a configuration for the given mail address and print it. This can be modified or
copied unchanged to the configuration file. Note that this only works for mail domains
that publish appropriate SRV records; see RFC 8314.
-S, --serverinfo
Print information about the POP3 server(s) and exit. This includes information about
supported features (pipelining, authentication methods, TOP command, ...), about parameters
(time for which mails will not be deleted, minimum time between logins, ...), and about the
TLS certificate (if TLS is active).
Configuration options
-C, --file=conffile
Use the given file instead of ~/.mpoprc or $XDG_CONFIG_HOME/mpop/config as the user
configuration file.
--host=hostname
Use this server with settings from the command line; do not use any configuration file
data. This option disables loading of the configuration file. You cannot use both this
option and account names on the command line.

USAGE
A suggestion for a suitable configuration file can be generated using the --configure option. The
default configuration file is ~/.mpoprc or $XDG_CONFIG_HOME/mpop/config. Settings in this file can be
changed by command line options.
A configuration file is a simple text file. Empty lines and comment lines (first non-blank character is
'#') are ignored. Every other line must contain a command and may contain an argument to that command.
The argument may be enclosed in double quotes (").
If a file name starts with the tilde (~), this tilde will be replaced by $HOME.
If a command accepts the argument on, it also accepts an empty argument and treats that as if it was on.
Commands are organized in accounts. Each account starts with the account command and defines the settings
for one POP3 account.
Commands are as follows:
defaults
Set defaults. The following configuration commands will set default values for all following
account definitions.
account name [:account[,...]]
Start a new account definition with the given name. The current default values are filled in.
If a colon and a list of previously defined accounts is given after the account name, the new
account, with the filled in default values, will inherit all settings from the accounts in the
list.
host hostname
The POP3 server to retrieve mails from. The argument may be a host name or a network address.
Every account definition must contain this command.
port number
The port that the POP3 server listens on. The default is 110 ("pop3"), unless TLS without STARTTLS
is used, in which case it is 995 ("pop3s").
source_ip [IP]
Set a source IP address to bind the outgoing connection to. Useful only in special cases on multi-
home systems. An empty argument disables this.
proxy_host [IP|hostname]
Use a SOCKS proxy. All network traffic will go through this proxy host, including DNS queries,
except for a DNS query that might be necessary to resolve the proxy host name itself (this can be
avoided by using an IP address as proxy host name). An empty hostname argument disables proxy
usage. The supported SOCKS protocol version is 5. If you want to use this with Tor, see also
"Using mpop with Tor" below.
proxy_port [number]
Set the port number for the proxy host. An empty number argument resets this to the default port,
which is 1080 ("socks").
socket socketname
Set the file name of a unix domain socket to connect to. This overrides both host/port and
proxy_host/proxy_port.
timeout (off|seconds)
Set or unset a network timeout, in seconds. The default is 180 seconds. The argument off means
that no timeout will be set, which means that the operating system default will be used.
pipelining (auto|on|off)
Enable or disable POP3 pipelining. You should never need to change the default setting, which is
auto: mpop enables pipelining for POP3 servers that advertise this capability, and disables it for
all other servers. Pipelining can speed up a POP3 session substantially.
auth [(on|method)]
Choose an authentication method. The default argument on chooses a method automatically.
Usually a user name and a password are used for authentication. The user name is specified in the
configuration file with the user command. There are five different methods to specify the
password:
1. Add the password to the system key ring. Currently supported key rings are the Gnome key ring
and the Mac OS X Keychain. For the Gnome key ring, use the command secret-tool (part of Gnome's
libsecret) to store passwords: secret-tool store --label=mpop host pop.freemail.example service
pop3 user joe.smith. On Mac OS X, use the following command: security add-internet-password -s
pop.freemail.example -r pop3 -a joe.smith -w. In both examples, replace pop.freemail.example with
the POP3 server name, and joe.smith with your user name.
2. Store the password in an encrypted files, and use passwordeval to specify a command to decrypt
that file, e.g. using GnuPG. See EXAMPLES.
3. Store the password in the configuration file using the password command. (Usually it is not
considered a good idea to store passwords in cleartext files. If you do it anyway, you must make
sure that the file can only be read by yourself.)
4. Store the password in ~/.netrc. This method is probably obsolete.
5. Type the password into the terminal when it is required.
It is recommended to use method 1 or 2.
Multiple authentication methods exist. Most servers support only some of them. Historically,
sophisticated methods were developed to protect passwords from being sent unencrypted to the
server, but nowadays everybody needs TLS anyway, so the simple methods suffice since the whole
session is protected. A suitable authentication method is chosen automatically, and when TLS is
disabled for some reason, only methods that avoid sending cleartext passwords are considered.
The following user / password methods are supported: user (a simple plain text method supported by
all servers), plain (another simple cleartext method, supported by almost all servers),
scram-sha-1 (a method that avoids cleartext passwords), scram-sha-256 (same but with stronger
hash), apop (an obsolete method that avoids cleartext passwords, but is not considered secure
anymore), cram-md5 (an obsolete method that avoids cleartext passwords, but is not considered
secure anymore), digest-md5 (an overcomplicated obsolete method that avoids cleartext passwords,
but is not considered secure anymore), login (a non-standard cleartext method similar to but worse
than the plain method), ntlm (an obscure non-standard method that is now considered broken; it
sometimes requires a special domain parameter passed via ntlmdomain).
There are currently three authentication methods that are not based on user / password information
and have to be chosen manually: oauthbearer or its predecessor xoauth2 (an OAuth2 token from the
mail provider is used as the password. See the documentation of your mail provider for details on
how to get this token. The passwordeval command can be used to pass the regularly changing tokens
into mpop from a script or an environment variable), external (the authentication happens outside
of the protocol, typically by sending a TLS client certificate, and the method merely confirms
that this authentication succeeded), and gssapi (the Kerberos framework takes care of secure
authentication, only a user name is required).
It depends on the underlying authentication library and its version whether a particular method is
supported or not. Use --version to find out which methods are supported.
user login
Set the user name for authentication. An empty argument unsets the user name.
password secret
Set the password for authentication. An empty argument unsets the password. Consider using the
passwordeval command or a key ring instead of this command, to avoid storing cleartext passwords
in the configuration file.
passwordeval [eval]
Set the password for authentication to the output (stdout) of the command eval. This can be used
e.g. to decrypt password files on the fly or to query key rings, and thus to avoid storing
cleartext passwords.
ntlmdomain [domain]
Set a domain for the ntlm authentication method. This is obsolete.
tls [(on|off)]
Enable or disable TLS (also known as SSL) for secured connections.
Transport Layer Security (TLS) "... provides communications privacy over the Internet. The
protocol allows client/server applications to communicate in a way that is designed to prevent
eavesdropping, tampering, or message forgery" (quote from RFC2246).
A server can use TLS in one of two modes: via a STARTTLS command (the session starts with the
normal protocol initialization, and TLS is then started using the protocol's STARTTLS command), or
immediately (TLS is initialized before the normal protocol initialization; this requires a
separate port). The first mode is the default, but you can switch to the second mode by disabling
tls_starttls.
When TLS is started, the server sends a certificate to identify itself. To verify the server
identity, a client program is expected to check that the certificate is formally correct and that
it was issued by a Certificate Authority (CA) that the user trusts. (There can also be certificate
chains with intermediate CAs.)
The list of trusted CAs is specified using the tls_trust_file command. The default value ist
"system" and chooses the system-wide default, but you can also choose the trusted CAs yourself.
A fundamental problem with this is that you need to trust CAs. Like any other organization, a CA
can be incompetent, malicious, subverted by bad people, or forced by government agencies to
compromise end users without telling them. All of these things happened and continue to happen
worldwide. The idea to have central organizations that have to be trusted for your communication
to be secure is fundamentally broken.
Instead of putting trust in a CA, you can choose to trust only a single certificate for the server
you want to connect to. For that purpose, specify the certificate fingerprint with
tls_fingerprint. This makes sure that no man-in-the-middle can fake the identity of the server by
presenting you a fraudulent certificate issued by some CA that happens to be in your trust list.
However, you have to update the fingerprint whenever the server certificate changes, and you have
to make sure that the change is legitimate each time, e.g. when the old certificate expired. This
is inconvenient, but it's the price to pay.
Information about a server certificate can be obtained with --serverinfo --tls
--tls-certcheck=off. This includes the issuer CA of the certificate (so you can trust that CA via
tls_trust_file), and the fingerprint of the certificate (so you can trust that particular
certificate via tls_fingerprint).
TLS also allows the server to verify the identity of the client. For this purpose, the client has
to present a certificate issued by a CA that the server trusts. To present that certificate, the
client also needs the matching key file. You can set the certificate and key files using
tls_cert_file and tls_key_file. This mechanism can also be used to authenticate users, so that
traditional user / password authentication is not necessary anymore. See the external mechanism in
auth.
You can also use client certificates stored on some external authentication device by specifying
GnuTLS device URIs in tls_cert_file and tls_key_file. You can find the correct URIs using p11tool
--list-privkeys --login (p11tool is bundled with GnuTLS). If your device requires a PIN to access
the data, you can specify that using one of the password mechanisms (e.g. passwordeval, password).
tls_starttls [(on|off)]
Choose the TLS variant: start TLS from within the session (on, default), or tunnel the session
through TLS (off).
tls_trust_file file
Activate server certificate verification using a list of trusted Certification Authorities (CAs).
The default is the special value "system", which selects the system default. An empty argument
disables trust in CAs. If you select a file, it must be in PEM format, and you should also use
tls_crl_file.
tls_crl_file [file]
Deprecated. This sets a certificate revocation list (CRL) file for TLS, to check for revoked
certificates (an empty argument, which is the default, disables this). Nowadays automatic OCSP
checks replace CRL file checks.
tls_fingerprint [fingerprint]
Set the fingerprint of a single certificate to accept for TLS. This certificate will be trusted
regardless of its contents (this overrides tls_trust_file). The fingerprint should be of type
SHA256, but can for backwards compatibility also be of type SHA1 or MD5 (please avoid this). The
format should be 01:23:45:67:.... Use --serverinfo --tls --tls-certcheck=off --tls-fingerprint=
to get the server certificate fingerprint.
tls_key_file file
Send a client certificate to the server (use this together with tls_cert_file}). The file must
contain the private key of a certificate in PEM format. An empty argument disables this feature.
tls_cert_file file
Send a client certificate to the server (use this together with tls_key_file). The file must
contain a certificate in PEM format. An empty argument disables this feature.
tls_certcheck [(on|off)]
Enable or disable checks of the server certificate. They are enabled by default. Disabling them
will override tls_trust_file and tls_fingerprint. WARNING: When the checks are disabled, TLS
sessions will not be secure!
tls_priorities [priorities]
Set priorities for TLS session parameters. The default is set by the TLS library and can be
selected by using an empty argument to this command. The interpretation of the priorities string
depends on the TLS library. Use --version to find out which TLS library you use.
For GnuTLS, see the section on Priority Strings in the manual.
For libtls, the priorites string is a space-separated list of parameter strings prefixed with
either PROTOCOLS=, CIPHERS=, or ECDHECURVES=. These parameter strings will be passed to the
functions tls_config_parse_protocols, tls_config_set_ciphers, and tls_config_set_ecdhecurves.
Unrecognized parts of the priorities string will be ignored. Example: "PROTOCOLS=TLSv1.3
CIPHERS=ECDHE-RSA-AES128-SHA256 ECDHECURVES=P-384".
tls_host_override [host]
By default, TLS host verification uses the host name given by the host command. This command
allows one to use a different host name for verification. This is only useful in special cases.
tls_min_dh_prime_bits [bits]
Deprecated, use tls_priorities instead. Set or unset the minimum number of Diffie-Hellman (DH)
prime bits accepted for TLS sessions. The default is set by the TLS library and can be selected by
using an empty argument to this command. Only lower the default (for example to 512 bits) if there
is no other way to make TLS work with the remote server.
delivery method method_arguments...
How to deliver messages received from this account.
delivery mda command
Deliver the mails through a mail delivery agent (MDA).
All occurrences of %F in the command will be replaced with the envelope from address of the
current message (or MAILER-DAEMON if none is found). Note that this address is guaranteed
to contain only letters a-z and A-Z, digits 0-9, and any of ".@_-+/", even though that is
only a subset of what is theoretically allowed in a mail address. Other characters,
including those interpreted by the shell, are replaced with "_". Nevertheless, you should
put %F into single quotes: '%F'.
Use "delivery mda /usr/bin/procmail -f '%F' -d $USER" for the procmail MDA.
Use "delivery mda /usr/sbin/sendmail -oi -oem -f '%F' -- $USER" to let your MTA handle the
mail.
Use "delivery mda /usr/local/bin/msmtp --host=localhost --from='%F' --
$USER@`hostname`.`dnsdomainname`" to pass the mail to your MTA via SMTP. (This is what
fetchmail does by default.)
delivery maildir directory
Deliver the mails to the given maildir directory. The directory must exist and it must have
the maildir subdirectories cur, new, and tmp; mpop will not create directories. This
delivery type only works on file systems that support hard links.
delivery mbox mbox-file
Deliver the mails to the given file in mbox format. The file will be locked with fcntl(2).
mpop uses the MBOXRD mbox format variant; see the documentation of the mbox format.
delivery exchange directory
Deliver the mails to the given Exchange pickup directory. The directory must exist.
If the delivery method needs to parse the mail headers for an envelope from address (the mda
method if the command contains %F, and the mbox method), then it needs to create a temporary file
to store the mail headers (but not the body) in. See $TMPDIR in the FILES / ENVIRONMENT section.
uidls_file filename
The file to store UIDLs in. These are needed to identify new messages. %U in the filename will be
replaced by the username of the current account. %H in the filename will be replaced by the
hostname of the current account. If the filename contains directories that do not exist, mpop
will create them. mpop locks this file for exclusive access when accessing the associated POP3
account.
The default value is "~/.mpop_uidls/%U_at_%H". You can also use a single UIDLS file for multiple
accounts, but then you cannot poll more than one of these accounts at the same time.
only_new [(on|off)]
By default, mpop processes only new messages (new messages are those that were not already
successfully retrieved in an earlier session). If this option is turned off, mpop will process all
messages.
keep [(on|off)]
Keep all mails on the POP3 server, never delete them. The default behaviour is to delete mails
that have been successfully retrieved or filtered by kill filters.
killsize (off|size)
Mails larger than the given size will be deleted (unless the keep command is used, in which case
they will just be skipped). The size argument must be zero or greater. If it is followed by a `k'
or an `m', the size is measured in kibibytes/mebibytes instead of bytes. Note that some POP3
servers report slightly incorrect sizes for mails; see NOTES below.
When killsize is set to 0 and keep is set to on, then all mails are marked as retrieved, but no
mail gets deleted from the server. This can be used to synchronize the UID list on the client to
the UID list on the server.
skipsize (off|size)
Mails larger than the given size will be skipped (not downloaded). The size argument must be zero
or greater. If it is followed by a `k' or an `m', the size is measured in kibibytes/mebibytes
instead of bytes. Note that some POP3 servers report slightly incorrect sizes for mails; see
NOTES below.
filter [command]
Set a filter which will decide whether to retrieve, skip, or delete each mail by investigating the
mail's headers. The POP3 server must support the POP3 TOP command for this to work; see option
--serverinfo above. An empty argument disables filtering.
All occurrences of %F in the command will be replaced with the envelope from address of the
current message (or MAILER-DAEMON if none is found). Note that this address is guaranteed to
contain only letters a-z and A-Z, digits 0-9, and any of ".@_-+/", even though that is only a
subset of what is theoretically allowed in a mail address. Other characters, including those
interpreted by the shell, are replaced with "_". Nevertheless, you should put %F into single
quotes: '%F'.
All occurrences of %S in the command will be replaced with the size of the current mail as
reported by the POP3 server.
The mail headers (plus the blank line separating the headers from the body) will be piped to the
command. Based on the return code, mpop decides what to do with the mail:
0: proceed normally; no special action
1: delete the mail; do not retrieve it
2: skip the mail; do not retrieve it
Return codes greater than or equal to 3 mean that an error occurred. The sysexits.h error codes
may be used to give information about the kind of the error, but this is not necessary.
received_header [(on|off)]
Enable or disable adding a Received header. By default, mpop prepends a Received header to the
mail during delivery. This is required by the RFCs if the mail is subsequently further delivered
e.g. via SMTP.
FILTERING
There are three filtering commands available. They will be executed in the following order:
killsize
skipsize
filter
If a filtering command applies to a mail, the remaining filters will not be executed.

# Host name of the POP3 server
host pop.freemail.example
# As an alternative to tls_trust_file, you can use tls_fingerprint
# to pin a single certificate. You have to update the fingerprint when the
# server certificate changes, but an attacker cannot trick you into accepting
# a fraudulent certificate. Get the fingerprint with
# $ mpop --serverinfo --tls --tls-certcheck=off --host=pop.freemail.example
#tls_fingerprint 00:11:22:33:44:55:66:77:88:99:AA:BB:CC:DD:EE:FF:00:11:22:33
# Authentication. The password is given using one of five methods, see below.
user joe.smith
# Password method 1: Add the password to the system keyring, and let mpop get
# it automatically. To set the keyring password using Gnome's libsecret:
# $ secret-tool store --label=mpop \
# host pop.freemail.example \
# service pop3 \
# user joe.smith
# Password method 2: Store the password in an encrypted file, and tell mpop
# which command to use to decrypt it. This is usually used with GnuPG, as in
# this example. Usually gpg-agent will ask once for the decryption password.
passwordeval gpg2 --no-tty -q -d ~/.mpop-password.gpg
# Password method 3: Store the password directly in this file. Usually it is not
# a good idea to store passwords in cleartext files. If you do it anyway, at
# least make sure that this file can only be read by yourself.
#password secret123
# Password method 4: Store the password in ~/.netrc. This method is probably not
# relevant anymore.
# Password method 5: Do not specify a password. Mpop will then prompt you for
# it. This means you need to be able to type into a terminal when mpop runs.
# A second mail box at the same freemail service
account freemail2 : freemail
user joey
# The POP3 server of your ISP
account isp
host mail.isp.example
auth on
user 12345
# Your ISP runs SpamAssassin, so test each mail for the "X-Spam-Status: Yes"
# header, and delete all mails with this header before downloading them.
filter if [ "`grep "^X-Spam-Status: Yes"`" ]; then exit 1; else exit 0; fi
# Set a default account
account default : freemail
Filtering with SpamAssassin
The command filter "/path/to/spamc -c > /dev/null" will delete all mails that SpamAssassin thinks are
spam. Since no message body is passed to SpamAssassin, you should disable all body-specific tests in the
SpamAssassin configuration file; for example set use_bayes 0.
If your mail provider runs SpamAssassin for you, you just have to check for the result. The following
script can do that when used as an mpop filter:
#!/bin/sh
if [ "`grep "^X-Spam-Status: Yes"`" ]; then
exit 1 # kill this message
else
exit 0 # proceed normally
fi
Since the filter command is passed to a shell, you can also use this directly:
filter if [ "`grep "^X-Spam-Status: Yes"`" ]; then exit 1; else exit 0; fi
Using mpop with Tor
Use the following settings:
proxy_host 127.0.0.1
proxy_port 9050
tls on
Use an IP address as proxy host name, so that mpop does not leak a DNS query when resolving it.
TLS is required to prevent exit hosts from reading your POP3 session.
FILES
~/.mpoprc or $XDG_CONFIG_HOME/mpop/config
Default configuration file.
~/.mpop_uidls
Default directory to store UIDLs files in.
~/.netrc and SYSCONFDIR/netrc
The netrc file contains login information. Before prompting for a password, msmtp will search it
in ~/.netrc and SYSCONFDIR/netrc.
ENVIRONMENT
$USER, $LOGNAME
These variables override the user's login name. $LOGNAME is only used if $USER is unset. The
user's login name is used for Received headers.
$TMPDIR
Directory to create temporary files in. If this is unset, a system specific default directory is
used.
