Sounds interesting. How do you "sandwich" the processes between network operation? I mean, postfix puts them out via LMTP to procmail, which does then - <what>? Invokes, after recipe processing, cyrus' deliver which then does LMTP again? So you have LMTP listeners (one procmail, one cyrus) on different IPs/Ifs or on different unix sockets? Regards, Birger
