Does anyone know of a good Postfix log file analysis program to find problems with particular users? In this instance I'm not interested in general statistics or anything. I just want to do searches such as "all attempts for @gmail.com accounts to send mail to user@example.com" where example.com is a local domain. The native Postfix logging has one line with a sender address and queue ID and later lines with the queue ID and the recipient(s) which may contain delivery errors. So I can't just grep for the data I want. My problem is when I get complains like "user@example.com can't receive mail from friend@gmail.com". In many cases it's trivial problems that can be difficult to diagnose, such as friend@gmail.com sending mail to user2@example.com where user2 has just added the sender to the spam list and not told anyone. So all parts of the server are working correctly but the users aren't getting what they want. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
