I'm trying to move our current listserv system to a new mail server (a Sun E420R) but I want to run it on it's own, virtual interface. I've got the interface set up as hme0:1 and I have a sendmail configuration also set up and bound to that interface. I've verified that the sendmail configuration works for both sending and receiving mail. However, I can't seem to get listserv to use anything other than the main system's port 25 when it processes outbound messages. The IP address on the virtual port has valid DNS entry's (forward and reverse) and I've got SMTP_HOSTNAME set to the corresponding host name in the go.user configuration file but still listserv insists on trying to connect to port 25 on the systems primary IP address when processing messages. Is there something I'm overlooking or is it simply not possible to run listserv in this fashion? Thanks for your time, Charlie
