issue with sieve forwarding after upgrade to 0.5.1

3 Apr 2018


      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 <http://server1.myserver.com/>[private/dovecot-lmtp] said: 451 4.2.0 <chris@mydomain.com <mailto: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 <mailto:chris@mydomain.com>>: Sendmail program returned error (temporary failure).
Any idea what is wrong?
Kind regards,
Christos Chatzaras
