Procmail filters don't seem to work

I've configured a few procmail filters and they don't seem to work. I've made the rule that mail from a certain sender should be moved to a mailfolder, that didn't work. Then I've tried to change the rule to throw away the mail when recieved, but that doesn't work either.

Is there any way to debug procmail?

There's a procmail logfile in /var/log/procmail.log.

If there are any errors/warnings, they'll show up in there.

Oh, and I didn't use the setup.sh...

I suspect not using the install.sh is the issue -- something in the mix isn't configured quite right. It's hard to tell exactly what, there's a lot of moving parts in this realm :-)

Do you see any errors in the mail log? If something is awry with Postfix or procmail, it may show up in the mail log.

Errors, yes, but not related I think.

Also not related.

It almost looks like procmail doesn't run.. or is it only invoked? (I'm kinda a procmail noob).

Since you have "LOGFILE=/var/log/procmail.log" set in the procmailrc, that's making me think procmail isn't running.

What permissions do you have set on /usr/bin/procmail? My system has:

[code:1]
ls -l /usr/bin/procmail
-rwsr-sr-x 1 root mail 72316 2007-03-27 14:35 /usr/bin/procmail
[/code:1]

However, normally Virtualmin uses this as the mailbox_home:

[code:1]mailbox_command = /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME[/code:1]

But that requires the procmail-wrapper package from the Virtualmin repository. Normally, that's setup by the installer -- but you can manually add the repository to your system, or even manually download the package from:

http://software.virtualmin.com/gpl/

But is procmail wrapper really needed? The perms:

Fluor:/home/thies # ls -l /usr/bin/procmail
-rwsr-sr-x 1 root root 74208 2007-08-02 18:50 /usr/bin/procmail

Further; I can't see a suitable source for SLES10, which I am running...

If procmail alone isn't working...then yeah, it's needed. ;-)

You can grab procmail-wrapper.c or the SRPM and build it yourself.

http://software.virtualmin.com/gpl/centos/5/SRPMS/procmail-wrapper-1.0-1...

rpmbuild --rebuild procmail-wrapper-1.0-1.vm.src.rpm

And then install the resulting package.

Hm. It's empty. Is that normal?

If procmail is working, then no, that's very abnormal :-)

It should be filled with all sorts of email delivery goodness (it should show information about every email delivery in there, successful or not).

Did you by chance install Virtualmin using the install.sh script?

If not, Postfix may not be configured to deliver using procmail. What is the "mailbox_command" set to in your /etc/postfix/main.cf file?

And what are the contents of your /etc/procmailrc file?

The contents of /etc/procmailrc:

--------

LOGFILE=/var/log/procmail.log
TRAP=/etc/webmin/virtual-server/procmail-logger.pl
:0wi
VIRTUALMIN=|/etc/webmin/virtual-server/lookup-domain.pl $LOGNAME
:0
* ?/usr/bin/test "$VIRTUALMIN" != ""
{
INCLUDERC=/etc/webmin/virtual-server/procmail/$VIRTUALMIN
}
ORGMAIL=$HOME/Maildir/
DEFAULT=$HOME/Maildir/
DROPPRIVS=yes
:0
* ^X-Spam-Status: Yes
Junk/

---------

the mailbox_command directive in main.cf is
mailbox_command = /usr/bin/procmail

which is correct, as I can see...

Okay, I've build and installed the wrapper succesfully; and changed the mailbox_command to

mailbox_command = /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME

and restarted postfix. However, no response in /var/log/procmail.log; any way to verify it's correct functioning?

No... it doesn't. I've tried sending a testmail:

May 28 11:38:57 Fluor postfix/qmgr[22204]: 319EF2E682EF: from=<thijs@XXX.nl>, size=23034, nrcpt=1 (queue active)

That seems like mailbox_command isn't set. Are you sure it isn't commented out or something?

It looks like you're right, but I've tried several options in main.cf and they won't load for some reason...

When I check the config in webmin:

main.cf

parameters defined as per defaults
command_directory /usr/sbin
config_directory /etc/postfix
debug_peer_level 2
defer_transports
disable_dns_lookups no
disable_mime_output_conversion no
inet_interfaces all
mail_owner postfix
mail_spool_directory /var/mail
mailbox_command
mailbox_transport

so no mailbox_command directive.

edit: my god, I'm stupid... it was put in the main.cf twice, and the last had precedence.

hi Joe, hi Eric,
I need some help concerning procmail too.
I used your install-script for setting up the system.
Following problem:
-If an e-mail user logs into his usermin account and sets a forwarding rule (forward to address xxx and deliver to mailbox), the forwarding doesn't work. delivering to the mailbox works.
-If the server-owner creates the same rule for the e-mail user in his virtualmin account, forwarding works fine.

There seems to be a problem with procmail because the logfile /var/log/procmail.log is empty, the result from:
[code:1]Jun 6 01:36:40 v10 procmail[14579]: Error while writing to "/var/log/procmail.log"

Hey,

I just setup a few filters in order to place messages coming from certain people into mailbox folders.

However, despite setting up the filters, the messages are all being sent to the INBOX.

I've checked the "procmail.log" file, and there are no errors.
