Hey thanks for the tip, Daniel. We do in fact have a Cisco 2600 series router, but I'm not sure if the IOS has any firewall features or not, I'll check now, though!

I don't know if this is happening in your instance, but I have seen that if you have a Cisco firewall, or a router running Cisco IOS firewall version that this can happen from the smtp fixup protocol. If you have one of those, check it for "fixup protocol smtp" or "ip inspect smtp" in the configuration. -Daniel ---------- Original Message ---------------------------------- From: "Andrew Forbes" <[EMAIL PROTECTED]> Reply-To: [EMAIL PROTECTED] Date: Thu, 22 Apr 2004 15:38:51 -0500 >Yes, when I'm making a telnet connection it is to port 25, thus: telnet >serverx.domain.com 25 > >Crap, I should have mentioned this, but after I make the above connection >attempt, I do actually get a connection.
