procmail won't remove spam from fetchmail'ed mail

alesz · 06-06-2006, 09:11 AM

I have set up fetchmail to fetch my mail from various mail servers to my desktop computer.
Mail gets delivered just fine, but I can't manage to persuade procmail to remove messages, marked as SPAM.

Probably mail isn't run trough procmail to filter it, i don't know. I've read several posts and tried couple of configurations, but I cannot manage to figure it out. My .forward file:

Code:

$ cat .forward
|/usr/bin/procmail

Procmail configuration file:

Code:

cat .procmailrc
PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin
MAILDIR=$HOME/Mail      #you'd better make sure it exists
DEFAULT=$MAILDIR/mbox   #completely optional
LOGFILE=$MAILDIR/from   #recommended

:0fw
| /usr/bin/spamassassin

:0
* ^Subject:.*SPAM*
/dev/null

:0
* ^Subject:[Spam*
/dev/null

My fetchmail configuration:

Code:

$cat .fetchmailrc
#set filter = /usr/bin/procmail -m $HOME/.procmailrc

set daemon 300
poll [server removed] with proto POP3
    user [user removed] there with password [pass removed] is ales here

poll [server removed] with proto POP3
    user [user removed]there with password [pass removed]is ales here

poll pop.gmail.com with proto POP3
    user [user removed]there with password [pass removed]is ales here

Google mail isn't delivered also, but that's another problem.
Can anyone tell, what could be wrong?

Check your LOGFILE. I send mail through SpamAssassin using spamc (less CPU intensive). I don't let SpamAssassin change the subject line, so I check for the presence of an "X-Spam-Flag" header instead:

Code:

:0:
* ^X-Spam-Flag:
$HOME/Spam

One more thing. The procmail matches regular expressions, in which '*' and '[' are metacharacters. So, for example, if you want to match "*SPAM*" in the subject line, your recipe would need to be

Code:

:0
* ^Subject:.*\*SPAM\*
/dev/null

I tried what you suggested, thanks, but it does not work.

First I tought this worked, but I am sorry, this does not work.

How could I even check, that procmail is run after mail is received? Which "LOGFILE" did you mean?

As per your .procmailrc, LOGFILE=$MAILDIR/from

You can also check /var/log/maillog, or whatever file your MTA logs to. For example, with Postfix, you'll have a line like this

Quote:

Jun 7 10:52:01 galois postfix/local[3213]: 1EC4218C35: to=<berhanie@example.com>, orig_to=<berhanie>, relay=local, delay=1, status=sent (delivered to command: /usr/bin/procmail)

Whereas, if mail isn't going through procmail, you'll have a line such as

Quote:

Jun 8 11:12:54 galois postfix/local[3227]: E411F18C35: to=<berhanie@example.com>, orig_to=<berhanie>, relay=local, delay=1, status=sent (delivered to mailbox)

Oh sorry, I see. But LOGFILE was not even created (mbox) in Mail/.
But I still don't know how to solve the problem. Does someone know about some gool tutorial that would work for FC5, as here apps are already installed/yum'med, so i'd need bare instructions?
