dovecot - May 2009 - using postfix+dovecot+squirrell+amavisd and spam folder per user

Hi All,

As I say in the subject I use postfix, dovecot with squirrellmail as webmail
and amavisd as spam control,

My problem is that all the spam I catch is send to /var/lib/amavis/virus but
I want to send this mails to the spam folder of each user.

This way the user can see the mails and determine if they are really spam or
false positive.

I dont know exactly what element of the system is the responsible to do that
(dovecot, amavis, posttix)

 any suggest? (although only be the initial point to look for it)

Thanks in advance

ESG

Hi,
 I would suggest you to use dovecot LDA (local delivery agent) and sieve
for mail sorting. Mail gets tagged by amavis/antispam and dovecot LDA
(run by postfix) places the junk mail to right folder based on your
sieve match on various headers.

Hi Karel,

Thank you very much for your answer,

I?m going to investigate lda as you say

In deed, I?m looking at my dovecot.conf and I realize I have this entry:

protocol lda {
postmaster_address = postmaster at dominio.com
mail_plugins = quota
log_path = /var/log/dovecot-deliver.log
info_log_path = /var/log/dovecot-deliver.log
}


I don?t know what is this for, but I?m going to investigate it.

On the other hand, I use mysql and virtual domains, is your answer valid for
this kind of configuration

thanks again,

ESG

HI again,

I cant get this work.

I have followed these instructions:

http://wiki.dovecot.org/LDA/Postfix

Now I have this in my configuratio files:

main.cf:
....
virtual_transport = dovecot
.....

master.cf:
....
dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -f ${sender}
-d ${recipient}
...

dovecot.conf:
protocol lda {
postmaster_address = postmaster at xeridia.com
mail_plugins = quota cmusieve
#sieve_global_dir = /etc/dovecot/sieve/
sieve = /etc/dovecot/sieve/dovecot.sieve
log_path = /var/log/dovecot-deliver.log
info_log_path = /var/log/dovecot-deliver.log
}


but when I send mails I don?t see that it uses dovecot lda at all:

this is an extract of the log:

I think I?m missing something, but I dont know what.

Show postconf -n output instead...

Did you reload postfix after making the change?
