Not sure if this means anything. This is the log from old server after trying 
to send. I edited the FQDN and IP though. Any thoughts? I think it may be the 
configuration of postfix on the new server though.

Oct  2 22:26:59 listservls01 postfix/smtp[139911]: B1FD27ED: 
to=<t...@listservnew.example.com>, orig_to=<olivert...@lists.luc.edu>, 
relay=listservnew.example.com[x.x.x.x]:25, delay=0.01, delays=0/0/0.01/0, dsn=4.4.2, 
status=deferred (lost connection with listservnew.example.com[x.x.x.x] while receiving the 
initial server greeting)

The message is deferred. Postfix will keep trying for maximal_queue_lifetime (default 5 days).

Possible causes are a firewall on the new server blocking port 25 connects or some postfix misconfiguration on that server. Can that server receive mail at all?
