Procmail and Sendmail

Someone correct me if I'm wrong, but I believe procmail is used for local delivery… you'd need to have configs set up in your .procmailrc file to pipe your mail through spamassassin before being inserted into your mailbox.

I know there are a lot of other ways to set these things up… The config I've used and have been happy with is using qmail for my MTA, with procmail for local delivery and a heavily customized .procmailrc file that not only runs it through spamassassin but also sorts into folders for me.

I guess the big question is, how many people are receiving mail through your system, and is it performing local delivery (for access either via a shell or POP or IMAP or something) to those users or is it relaying? If the mail is being relayed to a remote server, I have no idea how to get sendmail working with spamassassin for that…

Check /etc/mail/sendmail.mc - there should be FEATUREs related to

procmail, and also MAILER(procmail). Make sure they're uncommented,

and rerun m4 to generate a new sendmail.cf.
