I seem to remember something on this from the Postfix Users list. It had to do with the resolver configuration. Order of operations type of stuff. Something in the order earlier was answering up to Postfix, but dig was specifically calling the DNS and bypassing this. It is a shot in the dark, but that is the best I can do. > also, the ISP has installed the machines with journaling which is > destroying the performance (100 to 200 smtpd processes waiting on queue > access). Is it possible to turn of journaling without redoing the whole disk? EXT3? http://www.stahl.bau.tu-bs.de/~hildeb/postfix/postfix_ext3.shtml I know there are similar settings for other journaling systems. --Eric
