My first guess is your iptables configuratin is not letting smtp in. See if you can telnet to port 25 (smtp) from outside. If that works, look in /var/log/exim/* for a record of what went wrong before examining the exim.conf file for errors. If exim is really rejecting the messages then there should be something in the logs. Cheers! Shyamal -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
