We forgot to see whether their side might have legit/known reasons for rejecting the connection. For instance, Hank's 199.44.118.253 has no PTR (note it claims to be dns.mgtamer.com, but that hostname resolves to another IP, which has multiple PTRs).
When I EHLO into isbe.net, I don't get rejected and can send mail. But if I issue an RSET after my EHLO, then EHLO again, I get that fatal 503. So ME is indeed broken, in that (a) it seems to be erroneously issuing 502, when it needs to send a harder 5xx, to signal that it wants to break the connection outright, and (b) it certainly behaves in a draconian fashion if you issue an RSET from a previously allowed connection. But the root of the problem could still be on Hank's end. Sandy Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
