Courier Maildrop error user unknown. Command output: Invalid user specified
- by cad
Hello
I have a problem with maildrop. I have read dozens of webs/howto/emails but couldnt solve it.
My objective is moving automatically spam messages to a spam folder. My email server is working perfectly. It marks spam in subject and headers using spamassasin.
My box has:
Ubuntu 9.04
Web: Apache2 + Php5 + MySQL
MTA: Postfix 2.5.5 + SpamAssasin + virtual users using mysql
IMAP: Courier 0.61.2 + Courier AuthLib
WebMail: SquirrelMail
I have read that I could use Squirrelmail directly (not a good idea), procmail or maildrop. As I already have maildrop in the box (from courier)
I have configured the server to use maildrop (added an entry in transport table for a virtual domain).
I found this error in email:
This is the mail system at host foo.net

My config files:
http://lar3d.net/main.cf (/etc/postfix)
http://lar3d.net/master.c (/etc/postfix)
http://lar3d.net/local.cf (/etc/spamassasin)
http://lar3d.net/maildroprc (maildroprc)
If I change master.cf line (as suggested here)
maildrop unix - n n - - pipe
flags=DRhu user=vmail argv=/usr/lib/courier/bin/maildrop -d ${recipient}
with
maildrop unix - n n - - pipe
flags=DRhu user=vmail argv=/usr/lib/courier/bin/maildrop -d vmail ${recipient}
I get the email in /home/vmail/MailDir instead of the correct dir (/home/vmail/foo.net/info/.SPAM )
After reading a lot I have some guess but not sure.
- Maybe I have to install userdb?
- Maybe is something related with mysql, but everything is working ok
- If I try with procmail I will face same problem...
- What are flags DRhu for? Couldnt find doc about them
- In some places I found maildrop line with more parameters
flags=DRhu user=vmail argv=/usr/lib/courier/bin/maildrop -d $
${recipient} ${extension} ${recipient} ${user} ${nexthop} ${sender}
I am really lost. Dont know how to continue. If you have any idea or
need another config file please let me know.
Thanks!!!
