Hello,
I am currently testing the upgrade from our dovecot v2.2.23 to 2.3.0. I have a
strange problem with lda.
We use bounce mails for internal users if they try to send virus/spammails. The
exact same config works with 2.2.23, but not with 2.3.0.
The relevant postfix/master.cf part:
dovecot unix - n n - - pipe
flags=DRhu user=vmail:vmail argv=/opt/dovecot/libexec/dovecot/deliver -d
${recipient} -f ${sender}
On the same machine, with 2.2.23 I get a bounce mail when trying to send a
virus, with the subject "VIRUS in message apparently from you
(Eicar-Test-Signature)", to both the users inbox as well as to the mailbox of
virusalert@ourdomain.internal
With 2.3.0, in the logs I get an error:
relay=dovecot, delay=0.01, delays=0/0/0/0, dsn=5.3.0, status=bounced (command
line usage error. Command output: lda: Fatal: Invalid -f parameter: Missing
domain
and the alert message is only sent to virusalert@ourdomain.internal, but not to
the user who tried to send the mail.
The relevant part of our dovecot.conf:
protocol lda {
mail_plugins = " quota zlib sieve acl mail_log notify"
postmaster_address = postmaster@ourdomain.internal
}
Does anyone know how to solve this problem? Or is there a workaround via
postfix/amavis/spamassassin? Any hints are highly appreciated, thanks!
Regards,
infoomatic
