Hello Nicolas,

I tried the mailbox_transport = dovecot directive, with no luck, since I was using virtual mailboxes, where virtual_transport is responsible for delivery. What really helped, though, was the dovecot line in master.cf, which after a few tweaks allowed me to make things work eventually!

Thank you again for your help,

Hello,

I am currently running a similar setup, with spamc called per user at delivery time, from postfix. I use the following settings (on a Debian Etch system, so installation paths must be adapated).

• dovecot's deliver binary must be set setuid root,

• /etc/postfix/main.cf:

mailbox_transport = dovecot dovecot_destination_recipient_limit = 1

• /etc/postfix/master.cf:

# dovecot # dovecot unix - n n - 1 pipe flags=Rh user=dovecot argv=/usr/bin/spamc -u ${user} -e /usr/lib/dovecot/deliver -d ${user} -f ${sender}
