No bounce message when using horde as webmail

[xurubo93]

I can see that in PLESK 10.4.4 the following failure was reintroduced.

I also copied the mail-log entries

Mar 26 12:34:42 postfix/qmgr[29156]: CC63111D22F4: from=<me@dom.tld>, size=668, nrcpt=1 (queue active)
Mar 26 12:34:42 postfix-local[1182]: postfix-local: from=me@dom.tld, to=unknown.user@dom.tld, dirname=/var/qmail/mailnames
Mar 26 12:34:42 postfix-local[1182]: cannot chdir to mailname dir unknown.user: No such file or directory
Mar 26 12:34:42 postfix-local[1182]: Unknown user: unknown.user@dom.tld
Mar 26 12:34:42 postfix/pipe[1163]: CC63111D22F4: to=<unknown.user@dom.tld>, relay=plesk_virtual, delay=21, delays=21/0/0/0.06, dsn=2.0.0, status=sent (delivered via plesk_virtual service)
Mar 26 12:34:42 postfix/qmgr[29156]: CC63111D22F4: removed

You can see, that postfix tells you that this user cannot be found but the delivery was successful, so as a result no bounce message was sent.

Did someone else notice this behaviour?

Cheers

Try to configure horde to use SMTP instead of the local sendmail wrapper and retest.
