per user server side filtering for virtual users - MrRagga - 04-13-2008 12:31 PM

Hi,
I am wondering how to set up per user server side filtering as easy as possible. As far as i understand I can only use a procmailrc for local users, since virtual_transport is set to virtual. The server side filtering should be possible for every email account, so that i can filter every message to the appropriate maildir folder.
So what is the easiest solution to enable this? It doesn't matter if i use maildrop, procmail or whatever. I am just interested in that kind of solution without modifying too much.

Cheers Jonas

there's a post about doing this with procmail - but well, the forum is broken, so you won't find it...

Basically it this in the master.cf:

Code:

procmail  unix  -       n       n       -       -       pipe

    flags=DRhu user=vmail argv=/usr/bin/procmail HOME=/var/mail

    DEFAULT=/var/mail/virtual/${nexthop}/${user}/

then you can put a .procmailrc in every mail account

/var/mail/virtual/domain/user/.procmailrc

Give it a try...

Hi,
filtering does not work. Do I need to change the main.cf too? Do you have an example of a working procmailrc?

Yeah - I just found the original thread in archive.org

http://web.archive.org/web/20070629164310/http://www.isp-control.net/forum/procmail-bzw-procmailrc-verwenden-t-676.html

at least the first 10 posts...

You also need the following in main.cf:

Code:

virtual_transport = procmail

procmail_destination_recipient_limit = 1

(replace the actual virtual_transport...)

and a .procmailrc example, well some fragments and trials - I'll post the complete fragments...

Code:

# MAILDIR=$HOME/Maildir/

# DEFAULT=$MAILDIR

#VERBOSE=on

LOGFILE=$HOME/procmail.log

#LOGFILE="/var/log/procmail.log"

VERBOSE=yes

# MAILDIR=$DEFAULT

# FORMAIL=/usr/bin/formail

# SENDMAIL=/usr/sbin/sendmail

:0:

* ^X-Spam-Flag: YES

$DEFAULT.Spam/

This one just does some logging into /var/mail/procmail.log

-> HOME is HOME of user vmail...

You have to try with several variables $DEFAULT and others to get the MAILDIR root...

Would you mind trying this out and writing a howto which can be placed into the howto on this site?
