Thanks a lot, very nice solution.
But can you tell me, how to trigger a processing of messages, and
modify subject or other field in source message, for example? Or how
to modify body of message, using external linux commands like sed or
awk? This may be very useful, but I didn't find any examples of it on
Google yet.
