So I conclude, by dig and nslookup, that the NS's you "say" Imail is using both currently have cached the correct data for techie.com MX's and their A records. >That's it. What I looked for was another example of where I do an A record >look up and get the same result of just the name bouncing back at me. nslookup really, really sucks. Get the BIND tools pkg for Win32 here and use dig: ftp://ftp.isc.org/isc/bind/contrib/ntbind-8.3.3/BIND8.3.3Tools.zip > I just >registered with mail.com the e-mail [EMAIL PROTECTED] which also does not >return an IP when I do a nslookup on it. well, f@ck nslookup. As I say in my DNS classes for Men & Mice (where I actually go off-menu and present my own slides about DNS + mail), every mail admin really needs to be able to work with DNS. Knowing how to spell DNS isn't going to hack it. And DNS admins need to understand how SMTP uses DNS. So, and I'm just repeating what Scott has found, the DNS's your Imail is supposed to be using have correct data cached for techie.com. It's a very short path from Imail to those NS's. I suspect your problem is in the IMail machine, its tcp/ip stack, its DNS resolver, or connectivity between your Imail machine and its DNS's. Since Imail can send via the hosts file resolution, Imail has correct connectivity to the destination MTA. Imail weirdness has sometimes been linked to NIC cards and/or their drivers.
