Well now you're worrying me, because if this is something on their end, I know I'm going to have one heck of a time convincing them of that, even if I was fully versed on what I was talking about. The "client" in question is actually a university, so they have monster systems compared to mine and tend to look down on lowly, small companies like me. At least this university does.
The telnet program I'm using is just the one with Windows Server 2K, nothing more. I have no idea if it can do single packet responses, do you? Thanks for putting so much time in on this Scott.

It means that they are expecting your responses to be in just one packet each, whereas telnet will split up the responses into multiple packets. It's a common amateur mistake when writing server software. >I understand what you're saying about it being something I'm doing, but for >the life of me I don't what I'm doing wrong or missing here.

Most likely, those servers have some sort of firewall software that is blocking the connections, due to the multiple packets. If your telnet client allows it, you can have it send your responses in a single packet, which should bypass the firewall. -Scott --- Declude JunkMail: The advanced anti-spam solution for IMail mailservers since 2000.
