Assuming that the mail server’s routing table is correct, you will need some tcpdump to understand if the packets from outside reach the server (and then it discards them). I would do this: 1. Ensure that the mail server still has a valid default gateway and a correct routing table 2. start tcpdump on the gateway 3. start tcpdump on the mail server 4 Try to connect to the mail server from outside. > Greg Ciao, Andrea (just upgraded some servers, no problems) -- Andrea Dell'Amico http://adellam.sevenseas.org/
