Dovecot Sieve and Postfix header_checks Issue

[Alex Crow]

That would most likely be something in your header_checks that is 
causing the bounce from Sieve to be rejected.

There is no reason why you cannot use both.

If I vise versa turn off Dovecot Sieve then Postfix's header-checks are also working fine. However, when I keep them both turned on it also works but only partially and in this case Dovecot Sieve never bounces back any rejected massages remotely, the bounce happens only locally. That is I can see it in my logs that it was rejected locally but the message is never sent back to the sender saying something like, "Spam is rejected here". Thus the reject turns into a silent discard without telling the sender anything at all. Any ideas, help, advices how do I fix that? Would be really grateful for any suggestions / assistance at all. Many thanks in advance!

Postfix in its turn has a very neat feature of checking the headers via regexp but Postfix does not see / detect Spamassassin's added headers at all because I passed delivery and authentication (which is a way better than Postfix's) to dovecot deliver.
