The procmail (1) program can handle a user 's mail autonomously (for example, sorting incoming mail into folders based on subject) and can function as a sendmail delivery agent. Some administrators prefer procmail (1) in this latter role over normal Unix delivery agents . If this is your preference, you can easily use procmail (1) in that role with the local_procmail feature: FEATURE(`local_procmail') The local_procmail feature changes the P= , F= , and A= equates for the local delivery agent into: P=/usr/local/bin/procmail see P= F=SPfhn9 see F= A=procmail -Y -a $h -d $u see A= If you have installed procmail in a different location, you can specify that alternative location with a second argument: FEATURE(`local_procmail', `/admin/mail/bin/procmail') Beginning with V8.10, sendmail allows this local_procmail feature to accept additional arguments to define the A= values (set with LOCAL_MAILER_ARGS; See this section), and the F= values (set with LOCAL_MAILER_FLAGS; See this section). Those additional arguments were added to support other programs in addition to procmail (1), such as maildrop (1) and scanmails (1). [6] They are used like this:
FEATURE(`local_procmail', `/admin/mail/bin/procmail', ` A= stuff here ' , ` F= stuff here ' ) If you need to specify command-line arguments different from the defaults shown earlier, you can do so either with the second argument (the A= stuff here ), or by using the LOCAL_MAILER_ARGS (See this section) mc macro: FEATURE(`local_procmail') define(`LOCAL_MAILER_ARGS', `procmail -Y -a hidden.domain -d $u') If you need to use F= flags different from those shown, you can do so either with the third argument (the F= stuff here ), or by using the LOCAL_MAILER_FLAGS (See this section) mc macro: FEATURE(`local_procmail') define(`LOCAL_MAILER_FLAGS', `SPfhn') Both must follow the local_procmail feature. Use another program instead of procmailYou can also use the local_procmail feature (FEATURE(local_procmail)) to include support for the other programs. For example, the following line in your mc can be used to change the local delivery agent to use the maildrop (8) program: FEATURE(`local_procmail', `/usr/local/bin/maildrop', `maildrop -d $u') But before you do this, first create a configuration file without this feature that looks at the F= delivery agent equate for the local delivery agent. Then add the earlier line and create another configuration file. Note any differences between the F= delivery agent equates from the two configuration files and decide which are important to retain. If you decide that there are more F= delivery agent flags to retain than were created by the local_procmail feature, you can create a superset and add that superset declaration to the local_procmail feature like this: FEATURE(`local_procmail', `/usr/local/bin/maildrop', `maildrop -d $u', `SPfhn9A') The maildrop (8) program is intended for use only with Intel-based architectures, and is available with Debian GNU/Linux from http://packages.debian.org/stable/mail/maildrop.html. Note that, despite our description of maildrop (1) in this section, you can use this local_procmail feature to install other programs in the role of the local delivery program. But test carefully before releasing any new program in this role. |
