Hi Mark, Everything looks good from the netstat command.
I did get a connection refused with telnet. However, I then installed postfix on the host server and port 25 now seems to be open, yet no go so far on the messages. Just as a recap, I'm currently running mailman on a Ubuntu VM hosted on a Ubuntu server. Perhaps then I need to forward port 25 to the VM somehow? I did have this working fine from hard disks, but with some server troubles we wanted to keep mailman more self-contained.
