me, but before putting it into production, I would appreciate an

of seasoned procmail users.

You should never bounce messages taht have been accepted by your
mailserver as delivered.

Never.

Thanks for the reply! I would feel very much obliged if you could
clarify reasoning behind this statement or give a reference where
it is explained. My ultimate goal is to avoid losing forwarded
mail because of SPF. I am using postfix, and SRS is not supported
by it. Are there other solutions?

In case of traditional forwarding, the message can be bounced by
the final destination although it was earlier accepted by the
forwarder. So the problem with my setup is that the message is
bounced by the same host which accepted it earlier? Would sending
the bounce message from the same server but using different
hostname (DNS alias) make my setup comply with that "Never"?

Thanks,
Alex
