issue with sieve forwarding after upgrade to 0.5.1

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 <>[private/dovecot-lmtp] said: 451 4.2.0 <chris at <mailto:chris at>> 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 at <mailto:chris at>>: Sendmail program returned error (temporary failure).

Any idea what is wrong?

Kind regards,
