Hans Ginzel: > How to debug header_checks, please? Use Postfix logging. If you can't find it, then you need to fix your logging infrastructure which is not part of Postfix.
Perhaps it helps to turn off chroot: http://www.postfix.org/DEBUG_README.html#no_chroot. Header checks are logged by the cleanup daemon. > How should the postfix warning message look like in log file? The same text that you get with the "postmap -q" example. Postfix logs all mail activity. If you have no logs then you are blind. Wietse
