[linux] postfix

[Maria McKinley]

Hello there,

I am building a new mail server, and was looking at the configuration of the
old server and noticed two lines in master.cf for cyrus:

cyrus     unix  -       n       n       -       -       pipe
 flags=R user=cyrus argv=/usr/cyrus/bin/deliver -r ${sender} -m ${extension}
${user}

cyrus     unix  -       n       n       -       -       pipe
  flags=R user=cyrus argv=/usr/local/bin/spamfilter2 -e -m ${extension}
${user}

spamfilter2 just contains:
#!/bin/bash
/usr/bin/spamc | /usr/sbin/cyrdeliver "$@"
exit $?

Does anyone know what postfix does in the case of two entries for a service
in master.cf? The folder /usr/cyrus doesn't even exist, so I guess it must
be just skipping over the first cyrus line, since mail is being delivered...

I think the 2nd one is the one I really want, although I think I should have
the -r option. The -e option isn't on the man page, so not sure what that is
suppose to be doing.

Sanity check? Comments?

thanks,
maria
