Here are some logs:

Apr  3 23:25:35 server1 dovecot: lmtp(chris@coderz.gr)<47735><AUI6Aj/jw1p3ugAAPz4RRA>: program `/usr/sbin/sendmail' terminated with non-zero exit code 75
Apr  3 23:25:35 server1 dovecot: lmtp(chris@coderz.gr)<47735><AUI6Aj/jw1p3ugAAPz4RRA>: Error: sieve: msgid=<DE90EB45-9B58-4679-9BCE-E2698773519E@cretaforce.gr>: failed to redirect message to <chris@cretaforce.gr>: Sendmail program returned error (temporary failure)

In my postfix main.cf I have this:

authorized_submit_users = root, filter

When I change it to:

authorized_submit_users = root, filter, myUserName

where myUserName is the username that owns the mailbox it works.

So I guess that something changed to dovecot between 2.2.35 and 2.3.1 and is not related to pigeonhole.

Hello,

After I upgrade dovecot 2.2.35 to 2.3.1 and pigeonhole 0.4.23  to 0.5.1 when I use sieve to forward a message to other address using "redirect :copy" I get this:

(host server1.myserver.com[private/dovecot-lmtp] said: 451 4.2.0 <chris@mydomain.com> Execution of Sieve filters was aborted due to temporary failure (in reply to end of DATA command))

And in sieve log I see: failed to redirect message to <chris@mydomain.com>: Sendmail program returned error (temporary failure).

Any idea what is wrong?

Kind regards,
