Anyone Filter Email w/ Procmail
 

I am using Postfix to send and receive email on my email server and also have Spamassassin scoring incoming email. I was told that procmail can filter email from Spamassassin into a folder by placing a procmail.rc hidden file in the users home directory to then move mail labeled SPAM in the header into a specific folder. I would love to do this but don't know where to begin on setting something like this up. I am sick of having labeled SPAM in my inbox.

Bung this in a file at ~/.procmailrc
Note: It might be necessary to override your local delivery mechanism by also adding a .forward file that contains:
Or, you can change your delivery mechanism to include procmail - see your MTA docs about that.

Postfix will use procmail (they seem to hate it there for some reason), but I use maildrop for the same purpose.

There are a number of ways to do this, one is given above, or a few ways via the transport mechanism. Although for maildrop, I'm sure these would apply for procmail too.

AFAIK this isn't a standard location like ~/mail/. Consequence of using this location could result in the filesystem filling w/o users noticing.

May work for maildir?

OK - There is a lot of info here. Let me cap everything up. And by the way I Am using Maildir style, not sure if this makes any difference or not...

1 - I am going to touch ~/.procmailrc as Deleriux suggested.

2 - vim ~/.procmailrc & add what he suggested.

3 - Reload postfix and see if emails that are normally labeled [***** SPAM 6.7 *****] Increase Your Member Size in the subject get filtered w/o having to create a .forward file or adjusting any MTA (Postfix) settings.

Do I need to create ~/.spam or will the .procmailrc file auto generate this for me?

In my /etc/postfix/main.cf, I have the following entry commented out for procmail. Should I enable this setting? Not sure I understand what it does but it seems that it obviously relates to procmail and Postfix.

Personaly I dont like procmail as it such a cryptic syntax that isnt suitable for users to exploit. Although I didnt suggest it initially i would recommend as the above poster pointed out to use maildir instead of mbox since it is easier to read and simpler to administrate.

I am not sure I understand what you mean. I am using Maildir style messaging in Postfix rather than mbox as shown in my config:

How does this enable me to filter email that is labeled "SPAM"?

It was more to do with the procmail rule shown than the ability per se

So when I enable that comment in my postfix main.cf file, I no longer get email.

Should I not be using this option in my main.cf for procmail filtering?

That looks like the one

Which stops you getting email? If you mean the Maildir one, then mail is being sent to ~/Maildir in maildir format
