NAME

     spamass-milter — sendmail milter for passing emails through SpamAssassin

SYNOPSIS

     spamass-milter -p socket [-b|-B spamaddress] [-d debugflags] [-D host] [-e defaultdomain] [-f]
                    [-i networks] [-I] [-m] [-M] [-P pidfile] [-r nn] [-u defaultuser] [-x] [-- spamc flags ...]

DESCRIPTION

     The spamass-milter utility is a sendmail milter that checks and modifies incoming email messages with
     SpamAssassin.

     The following options are available:

     -p socket
             Specifies the pathname of a socket to create for communication with sendmail.  If it is removed,
             sendmail will not be able to access the milter.  This may cause messages to bounce, queue, or be
             passed through unmiltered, depending on the parameters in sendmail's .cf file.

     -b spamaddress
             Redirects tagged spam to the specified email address.  All envelope recipients are removed, and
             inserted into the message as ‘X-Spam-Orig-To:’ headers.

     -B spamaddress
             Same as -b, except the original recipients are retained.  Only one of -b and -B may be used.

     -d debugflags
             Enables logging.  debugflags is a comma-separated list of tokens:

             func    Entry and exit of internal functions.

             misc    Other non-verbose logging.

             net     Lookups of the ignored netblocks list.

             poll    Low-level I/O to the child spamc process.

             rcpt    Recipient processing.

             spamc   High-level I/O to the child spamc process.

             str     Calls to field lookup and string comparison functions.

             uori    Calls to the update_or_insert function.

             1       (historical) Same as func,misc.

             2       (historical) Same as func,misc,poll.

             3       (historical) Same as func,misc,poll,str,uori.

     -D host
             Connects to a remote spamd server on host, instead of using one on localhost.  This option is
             deprecated; use -- -d host instead.

     -e defaultdomain
             Pass the full user@domain address to spamc.  The default is to pass only the username part on the
             assumption that all users are local.  This flag is useful if you are using an SQL (or other
             username) backend with spamassassin and have listed the full address there.  If the recipient name
             has no domain part (if the recipient is on the local machine for example), defaultdomain is added.
             Requires the -u flag.

     -f      Causes spamass-milter to fork into the background.

     -i networks
             Ignores messages if the originating IP is in the network(s) listed.  The message will be passed
             through without calling SpamAssassin at all.  networks is a comma-separated list, where each
             element can be either an IP address (nnn.nnn.nnn.nnn), a CIDR network (nnn.nnn.nnn.nnn/nn), or a
             network/netmask pair (nnn.nnn.nnn.nnn/nnn.nnn.nnn.nnn).  Multiple -i flags will append to the list.
             For example, if you list all your internal networks, no outgoing emails will be filtered.

     -I      Ignores messages if the sender has authenticated via SMTP AUTH.

     -m      Disables modification of the ‘Subject:’ and ‘Content-Type:’ headers and message body.  This is
             useful when SpamAssassin is configured with ‘defang_mime 0’ and ‘report_header 1’, or when SA is
             simply used to add headers for postprocessing later.  Updating the body through the milter
             interface can be slow for large messages.

     -M      Like -m, but also disables creation of any SpamAssassin ‘X-Spam-*’ headers as well.  Both tagged
             and untagged mail gets passed through unchanged.  To be useful, this option should be used with the
             -r, -b, or -B flags.  If -b is used, the ‘X-Spam-Orig-To:’ headers will still be added.

     -P pidfile
             Create the file pidfile, containing the processid of the milter.

     -r nn   Reject scanned email if it greater than or equal to nn.  If -1, reject scanned email if
             SpamAssassin tags it as spam (useful if you are also using the -u flag, and users have changed
             their required_hits value).

             For example, if you usually use procmail to redirect tagged email into a separate folder just in
             case of false positives, you can use -r 15 and reject flagrant spam outright while still receiving
             low-scoring messages.

     -u defaultuser
             Pass the username part of the first recipient to spamc with the -u flag.  This allows user
             preferences files to be used.  If the message is addressed to multiple recipients, the username
             defaultuser is passed instead.

             Note that spamass-milter does not know whether an email is incoming or outgoing, so a message from
             ⟨user1@localdomain.com⟩ to ⟨user2@yahoo.com⟩ will make spamass-milter pass -u user2 to spamc.

     -x      Pass the recipient address through sendmail -bv, which will perform virtusertable and alias
             expansion.  The resulting username is then passed to spamc.  Requires the -u flag.

     -- spamc flags ...
             Pass all remaining options to spamc.  This allows you to connect to a remote spamd with -d or -p.
