The problem was solved with a full server reboot (rebooting the zone where Postfix is running did not help). Strange....but I'm happy for now.

The binaries used are compiled on a Solaris server and have been in use since September 21st last year without any problems until yesterday when they suddenly stopped working. I replaced them with the exact same binaries that was used when the server was upgraded on September 21st (didn't help). They are also in use on two other servers where they are working prefectly (thank god for that) and they were compiled the same way as version 2.6.4 and 2.7.1 that were used before this version ( 2.8.5) and those versions worked without problems. Something happpend after a restart when I made changed´s to the parameters in main.cf (No changes whatsoever was made with the binaries used).

My reply was 100% about the consequences of replacing Postfix binaries of build X with Postfix binaries of build Y, where X does not equal Y. You now have a master daemon process of build X, executing binaries of build Y. Wietse
