NAME
git-send-email - Send a collection of patches as emails
SYNOPSIS
git send-email [<options>] (<file>|<directory>)...
git send-email [<options>] <format-patch-options>
git send-email --dump-aliases
git send-email --translate-aliases
DESCRIPTION
Takes the patches given on the command line and emails them out. Patches can be specified as files,
directories (which will send all files in the directory), or directly as a revision list. In the last
case, any format accepted by git-format-patch(1) can be passed to git send-email, as well as options
understood by git-format-patch(1).
The header of the email is configurable via command-line options. If not specified on the command line,
the user will be prompted with a ReadLine enabled interface to provide the necessary information.
There are two formats accepted for patch files:
1. mbox format files
This is what git-format-patch(1) generates. Most headers and MIME formatting are ignored.
2. The original format used by Greg Kroah-Hartman’s send_lots_of_email.pl script
This format expects the first line of the file to contain the "Cc:" value and the "Subject:" of the
message as the second line.
OPTIONS
Composing
--annotate
Review and edit each patch you’re about to send. Default is the value of sendemail.annotate. See the
CONFIGURATION section for sendemail.multiEdit.
--bcc=<address>,...
Specify a "Bcc:" value for each email. Default is the value of sendemail.bcc.
This option may be specified multiple times.
--cc=<address>,...
Specify a starting "Cc:" value for each email. Default is the value of sendemail.cc.
This option may be specified multiple times.
--compose
Invoke a text editor (see GIT_EDITOR in git-var(1)) to edit an introductory message for the patch
series.
When --compose is used, git send-email will use the From, To, Cc, Bcc, Subject, Reply-To, and
In-Reply-To headers specified in the message. If the body of the message (what you type after the
headers and a blank line) only contains blank (or Git: prefixed) lines, the summary won’t be sent,
but the headers mentioned above will be used unless they are removed.
Missing From or In-Reply-To headers will be prompted for.
See the CONFIGURATION section for sendemail.multiEdit.
--from=<address>
Specify the sender of the emails. If not specified on the command line, the value of the
sendemail.from configuration option is used. If neither the command-line option nor sendemail.from
are set, then the user will be prompted for the value. The default for the prompt will be the value
of GIT_AUTHOR_IDENT, or GIT_COMMITTER_IDENT if that is not set, as returned by "git var -l".
--reply-to=<address>
Specify the address where replies from recipients should go to. Use this if replies to messages
should go to another address than what is specified with the --from parameter.
--in-reply-to=<identifier>
Make the first mail (or all the mails with --no-thread) appear as a reply to the given Message-ID,
which avoids breaking threads to provide a new patch series. The second and subsequent emails will be
sent as replies according to the --[no-]chain-reply-to setting.
So for example when --thread and --no-chain-reply-to are specified, the second and subsequent patches
will be replies to the first one like in the illustration below where [PATCH v2 0/3] is in reply to
[PATCH 0/2]:
[PATCH 0/2] Here is what I did...
[PATCH 1/2] Clean up and tests
[PATCH 2/2] Implementation
[PATCH v2 0/3] Here is a reroll
[PATCH v2 1/3] Clean up
[PATCH v2 2/3] New tests
[PATCH v2 3/3] Implementation
Only necessary if --compose is also set. If --compose is not set, this will be prompted for.
--subject=<string>
Specify the initial subject of the email thread. Only necessary if --compose is also set. If
--compose is not set, this will be prompted for.
--to=<address>,...
Specify the primary recipient of the emails generated. Generally, this will be the upstream
maintainer of the project involved. Default is the value of the sendemail.to configuration value; if
that is unspecified, and --to-cmd is not specified, this will be prompted for.
This option may be specified multiple times.
--8bit-encoding=<encoding>
When encountering a non-ASCII message or subject that does not declare its encoding, add
headers/quoting to indicate it is encoded in <encoding>. Default is the value of the
sendemail.assume8bitEncoding; if that is unspecified, this will be prompted for if any non-ASCII
files are encountered.
Note that no attempts whatsoever are made to validate the encoding.
--compose-encoding=<encoding>
Specify encoding of compose message. Default is the value of the sendemail.composeEncoding; if that
is unspecified, UTF-8 is assumed.
--transfer-encoding=(7bit|8bit|quoted-printable|base64|auto)
Specify the transfer encoding to be used to send the message over SMTP. 7bit will fail upon
encountering a non-ASCII message. quoted-printable can be useful when the repository contains files
that contain carriage returns, but makes the raw patch email file (as saved from a MUA) much harder
to inspect manually. base64 is even more fool proof, but also even more opaque. auto will use 8bit
when possible, and quoted-printable otherwise.
Default is the value of the sendemail.transferEncoding configuration value; if that is unspecified,
default to auto.
--xmailer, --no-xmailer
Add (or prevent adding) the "X-Mailer:" header. By default, the header is added, but it can be turned
off by setting the sendemail.xmailer configuration variable to false.
Sending
--envelope-sender=<address>
Specify the envelope sender used to send the emails. This is useful if your default address is not
the address that is subscribed to a list. In order to use the From address, set the value to "auto".
If you use the sendmail binary, you must have suitable privileges for the -f parameter. Default is
the value of the sendemail.envelopeSender configuration variable; if that is unspecified, choosing
the envelope sender is left to your MTA.
--sendmail-cmd=<command>
Specify a command to run to send the email. The command should be sendmail-like; specifically, it
must support the -i option. The command will be executed in the shell if necessary. Default is the
value of sendemail.sendmailCmd. If unspecified, and if --smtp-server is also unspecified,
git-send-email will search for sendmail in /usr/sbin, /usr/lib and $PATH.
--smtp-encryption=<encryption>
Specify in what way encrypting begins for the SMTP connection. Valid values are ssl and tls. Any
other value reverts to plain (unencrypted) SMTP, which defaults to port 25. Despite the names, both
values will use the same newer version of TLS, but for historic reasons have these names. ssl refers
to "implicit" encryption (sometimes called SMTPS), that uses port 465 by default. tls refers to
"explicit" encryption (often known as STARTTLS), that uses port 25 by default. Other ports might be
used by the SMTP server, which are not the default. Commonly found alternative port for tls and
unencrypted is 587. You need to check your provider’s documentation or your server configuration to
make sure for your own case. Default is the value of sendemail.smtpEncryption.
--smtp-domain=<FQDN>
Specifies the Fully Qualified Domain Name (FQDN) used in the HELO/EHLO command to the SMTP server.
Some servers require the FQDN to match your IP address. If not set, git send-email attempts to
determine your FQDN automatically. Default is the value of sendemail.smtpDomain.
--smtp-auth=<mechanisms>
Whitespace-separated list of allowed SMTP-AUTH mechanisms. This setting forces using only the listed
mechanisms. Example:
$ git send-email --smtp-auth="PLAIN LOGIN GSSAPI" ...
If at least one of the specified mechanisms matches the ones advertised by the SMTP server and if it
is supported by the utilized SASL library, the mechanism is used for authentication. If neither
sendemail.smtpAuth nor --smtp-auth is specified, all mechanisms supported by the SASL library can be
used. The special value none maybe specified to completely disable authentication independently of
--smtp-user
--smtp-pass[=<password>]
Password for SMTP-AUTH. The argument is optional: If no argument is specified, then the empty string
is used as the password. Default is the value of sendemail.smtpPass, however --smtp-pass always
overrides this value.
Furthermore, passwords need not be specified in configuration files or on the command line. If a
username has been specified (with --smtp-user or a sendemail.smtpUser), but no password has been
specified (with --smtp-pass or sendemail.smtpPass), then a password is obtained using git-credential.
--no-smtp-auth
Disable SMTP authentication. Short hand for --smtp-auth=none
--smtp-server=<host>
If set, specifies the outgoing SMTP server to use (e.g. smtp.example.com or a raw IP address). If
unspecified, and if --sendmail-cmd is also unspecified, the default is to search for sendmail in
/usr/sbin, /usr/lib and $PATH if such a program is available, falling back to localhost otherwise.
For backward compatibility, this option can also specify a full pathname of a sendmail-like program
instead; the program must support the -i option. This method does not support passing arguments or
using plain command names. For those use cases, consider using --sendmail-cmd instead.
--smtp-server-port=<port>
Specifies a port different from the default port (SMTP servers typically listen to smtp port 25, but
may also listen to submission port 587, or the common SSL smtp port 465); symbolic port names (e.g.
"submission" instead of 587) are also accepted. The port can also be set with the
sendemail.smtpServerPort configuration variable.
--smtp-server-option=<option>
If set, specifies the outgoing SMTP server option to use. Default value can be specified by the
sendemail.smtpServerOption configuration option.
The --smtp-server-option option must be repeated for each option you want to pass to the server.
Likewise, different lines in the configuration files must be used for each option.
--smtp-ssl
Legacy alias for --smtp-encryption ssl.
--smtp-ssl-cert-path
Path to a store of trusted CA certificates for SMTP SSL/TLS certificate validation (either a
directory that has been processed by c_rehash, or a single file containing one or more PEM format
certificates concatenated together: see verify(1) -CAfile and -CApath for more information on these).
Set it to an empty string to disable certificate verification. Defaults to the value of the
sendemail.smtpSSLCertPath configuration variable, if set, or the backing SSL library’s compiled-in
default otherwise (which should be the best choice on most platforms).
--smtp-user=<user>
Username for SMTP-AUTH. Default is the value of sendemail.smtpUser; if a username is not specified
(with --smtp-user or sendemail.smtpUser), then authentication is not attempted.
--smtp-debug=(0|1)
Enable (1) or disable (0) debug output. If enabled, SMTP commands and replies will be printed. Useful
to debug TLS connection and authentication problems.
--batch-size=<num>
Some email servers (e.g. smtp.163.com) limit the number emails to be sent per session (connection)
and this will lead to a failure when sending many messages. With this option, send-email will
disconnect after sending $<num> messages and wait for a few seconds (see --relogin-delay) and
reconnect, to work around such a limit. You may want to use some form of credential helper to avoid
having to retype your password every time this happens. Defaults to the sendemail.smtpBatchSize
configuration variable.
--relogin-delay=<int>
Waiting $<int> seconds before reconnecting to SMTP server. Used together with --batch-size option.
Defaults to the sendemail.smtpReloginDelay configuration variable.
Automating
--no-to, --no-cc, --no-bcc
Clears any list of "To:", "Cc:", "Bcc:" addresses previously set via config.
--no-identity
Clears the previously read value of sendemail.identity set via config, if any.
--to-cmd=<command>
Specify a command to execute once per patch file which should generate patch file specific "To:"
entries. Output of this command must be single email address per line. Default is the value of
sendemail.toCmd configuration value.
--cc-cmd=<command>
Specify a command to execute once per patch file which should generate patch file specific "Cc:"
entries. Output of this command must be single email address per line. Default is the value of
sendemail.ccCmd configuration value.
--header-cmd=<command>
Specify a command that is executed once per outgoing message and output RFC 2822 style header lines
to be inserted into them. When the sendemail.headerCmd configuration variable is set, its value is
always used. When --header-cmd is provided at the command line, its value takes precedence over the
sendemail.headerCmd configuration variable.
--no-header-cmd
Disable any header command in use.
--[no-]chain-reply-to
If this is set, each email will be sent as a reply to the previous email sent. If disabled with
"--no-chain-reply-to", all emails after the first will be sent as replies to the first email sent.
When using this, it is recommended that the first file given be an overview of the entire patch
series. Disabled by default, but the sendemail.chainReplyTo configuration variable can be used to
enable it.
--identity=<identity>
A configuration identity. When given, causes values in the sendemail.<identity> subsection to take
precedence over values in the sendemail section. The default identity is the value of
sendemail.identity.
--[no-]signed-off-by-cc
If this is set, add emails found in the Signed-off-by trailer or Cc: lines to the cc list. Default is
the value of sendemail.signedOffByCc configuration value; if that is unspecified, default to
--signed-off-by-cc.
--[no-]cc-cover
If this is set, emails found in Cc: headers in the first patch of the series (typically the cover
letter) are added to the cc list for each email set. Default is the value of sendemail.ccCover
configuration value; if that is unspecified, default to --no-cc-cover.
--[no-]to-cover
If this is set, emails found in To: headers in the first patch of the series (typically the cover
letter) are added to the to list for each email set. Default is the value of sendemail.toCover
configuration value; if that is unspecified, default to --no-to-cover.
--suppress-cc=<category>
Specify an additional category of recipients to suppress the auto-cc of:
• author will avoid including the patch author.
• self will avoid including the sender.
• cc will avoid including anyone mentioned in Cc lines in the patch header except for self (use
self for that).
• bodycc will avoid including anyone mentioned in Cc lines in the patch body (commit message)
except for self (use self for that).
• sob will avoid including anyone mentioned in the Signed-off-by trailers except for self (use self
for that).
• misc-by will avoid including anyone mentioned in Acked-by, Reviewed-by, Tested-by and other "-by"
lines in the patch body, except Signed-off-by (use sob for that).
• cccmd will avoid running the --cc-cmd.
• body is equivalent to sob + bodycc + misc-by.
• all will suppress all auto cc values.
Default is the value of sendemail.suppressCc configuration value; if that is unspecified, default to
self if --suppress-from is specified, as well as body if --no-signed-off-cc is specified.
--[no-]suppress-from
If this is set, do not add the From: address to the cc: list. Default is the value of
sendemail.suppressFrom configuration value; if that is unspecified, default to --no-suppress-from.
--[no-]thread
If this is set, the In-Reply-To and References headers will be added to each email sent. Whether each
mail refers to the previous email (deep threading per git format-patch wording) or to the first email
(shallow threading) is governed by "--[no-]chain-reply-to".
If disabled with "--no-thread", those headers will not be added (unless specified with
--in-reply-to). Default is the value of the sendemail.thread configuration value; if that is
unspecified, default to --thread.
It is up to the user to ensure that no In-Reply-To header already exists when git send-email is asked
to add it (especially note that git format-patch can be configured to do the threading itself).
Failure to do so may not produce the expected result in the recipient’s MUA.
--[no-]mailmap
Use the mailmap file (see gitmailmap(5)) to map all addresses to their canonical real name and email
address. Additional mailmap data specific to git-send-email may be provided using the
sendemail.mailmap.file or sendemail.mailmap.blob configuration values. Defaults to sendemail.mailmap.
Administering
--confirm=<mode>
Confirm just before sending:
• always will always confirm before sending
• never will never confirm before sending
• cc will confirm before sending when send-email has automatically added addresses from the patch
to the Cc list
• compose will confirm before sending the first message when using --compose.
• auto is equivalent to cc + compose
Default is the value of sendemail.confirm configuration value; if that is unspecified, default to
auto unless any of the suppress options have been specified, in which case default to compose.
--dry-run
Do everything except actually send the emails.
--[no-]format-patch
When an argument may be understood either as a reference or as a file name, choose to understand it
as a format-patch argument (--format-patch) or as a file name (--no-format-patch). By default, when
such a conflict occurs, git send-email will fail.
--quiet
Make git-send-email less verbose. One line per email should be all that is output.
--[no-]validate
Perform sanity checks on patches. Currently, validation means the following:
• Invoke the sendemail-validate hook if present (see githooks(5)).
• Warn of patches that contain lines longer than 998 characters unless a suitable transfer encoding
(auto, base64, or quoted-printable) is used; this is due to SMTP limits as described by
https://www.ietf.org/rfc/rfc5322.txt.
Default is the value of sendemail.validate; if this is not set, default to --validate.
--force
Send emails even if safety checks would prevent it.
Information
--dump-aliases
Instead of the normal operation, dump the shorthand alias names from the configured alias file(s),
one per line in alphabetical order. Note that this only includes the alias name and not its expanded
email addresses. See sendemail.aliasesFile for more information about aliases.
--translate-aliases
Instead of the normal operation, read from standard input and interpret each line as an email alias.
Translate it according to the configured alias file(s). Output each translated name and email address
to standard output, one per line. See sendemail.aliasFile for more information about aliases.
CONFIGURATION
Everything below this line in this section is selectively included from the git-config(1) documentation. The content is the same as what’s found there: sendemail.identity A configuration identity. When given, causes values in the sendemail.<identity> subsection to take precedence over values in the sendemail section. The default identity is the value of sendemail.identity. sendemail.smtpEncryption See git-send-email(1) for description. Note that this setting is not subject to the identity mechanism. sendemail.smtpSSLCertPath Path to ca-certificates (either a directory or a single file). Set it to an empty string to disable certificate verification. sendemail.<identity>.* Identity-specific versions of the sendemail.* parameters found below, taking precedence over those when this identity is selected, through either the command-line or sendemail.identity. sendemail.multiEdit If true (default), a single editor instance will be spawned to edit files you have to edit (patches when --annotate is used, and the summary when --compose is used). If false, files will be edited one after the other, spawning a new editor each time. sendemail.confirm Sets the default for whether to confirm before sending. Must be one of always, never, cc, compose, or auto. See --confirm in the git-send-email(1) documentation for the meaning of these values. sendemail.mailmap If true, makes git-send-email(1) assume --mailmap, otherwise assume --no-mailmap. False by default. sendemail.mailmap.file The location of a git-send-email(1) specific augmenting mailmap file. The default mailmap and mailmap.file are loaded first. Thus, entries in this file take precedence over entries in the default mailmap locations. See gitmailmap(5). sendemail.mailmap.blob Like sendemail.mailmap.file, but consider the value as a reference to a blob in the repository. Entries in sendemail.mailmap.file take precedence over entries here. See gitmailmap(5). sendemail.aliasesFile To avoid typing long email addresses, point this to one or more email aliases files. You must also supply sendemail.aliasFileType. sendemail.aliasFileType Format of the file(s) specified in sendemail.aliasesFile. Must be one of mutt, mailrc, pine, elm, gnus, or sendmail. What an alias file in each format looks like can be found in the documentation of the email program of the same name. The differences and limitations from the standard formats are described below: sendmail • Quoted aliases and quoted addresses are not supported: lines that contain a " symbol are ignored. • Redirection to a file (/path/name) or pipe (|command) is not supported. • File inclusion (:include: /path/name) is not supported. • Warnings are printed on the standard error output for any explicitly unsupported constructs, and any other lines that are not recognized by the parser. sendemail.annotate, sendemail.bcc, sendemail.cc, sendemail.ccCmd, sendemail.chainReplyTo, sendemail.envelopeSender, sendemail.from, sendemail.headerCmd, sendemail.signedOffByCc, sendemail.smtpPass, sendemail.suppressCc, sendemail.suppressFrom, sendemail.to, sendemail.toCmd, sendemail.smtpDomain, sendemail.smtpServer, sendemail.smtpServerPort, sendemail.smtpServerOption, sendemail.smtpUser, sendemail.thread, sendemail.transferEncoding, sendemail.validate, sendemail.xmailer These configuration variables all provide a default for git-send-email(1) command-line options. See its documentation for details. sendemail.signedOffCc (deprecated) Deprecated alias for sendemail.signedOffByCc. sendemail.smtpBatchSize Number of messages to be sent per connection, after that a relogin will happen. If the value is 0 or undefined, send all messages in one connection. See also the --batch-size option of git-send- email(1). sendemail.smtpReloginDelay Seconds to wait before reconnecting to the smtp server. See also the --relogin-delay option of git- send-email(1). sendemail.forbidSendmailVariables To avoid common misconfiguration mistakes, git-send-email(1) will abort with a warning if any configuration options for "sendmail" exist. Set this variable to bypass the check.
EXAMPLES
Use gmail as the smtp server
To use git send-email to send your patches through the GMail SMTP server, edit ~/.gitconfig to specify
your account settings:
[sendemail]
smtpEncryption = tls
smtpServer = smtp.gmail.com
smtpUser = yourname@gmail.com
smtpServerPort = 587
If you have multi-factor authentication set up on your Gmail account, you can generate an app-specific
password for use with git send-email. Visit https://security.google.com/settings/security/apppasswords to
create it.
Once your commits are ready to be sent to the mailing list, run the following commands:
$ git format-patch --cover-letter -M origin/master -o outgoing/
$ edit outgoing/0000-*
$ git send-email outgoing/*
The first time you run it, you will be prompted for your credentials. Enter the app-specific or your
regular password as appropriate. If you have credential helper configured (see git-credential(1)), the
password will be saved in the credential store so you won’t have to type it the next time.
Note: the following core Perl modules that may be installed with your distribution of Perl are required:
MIME::Base64, MIME::QuotedPrint, Net::Domain and Net::SMTP. These additional Perl modules are also
required: Authen::SASL and Mail::Address.
