You went through the troubleshooting process. You defined the problem and
then gathered data. I never said go through the OSI layers as you may be
implying. I said to use Cisco's troubleshooting method as taught in CIT and
probably still at the bottom of this message. There's no mention of OSI in

Hi All,
A small thing on this. Cross check whenever you are putting that router,
what is the default gateway. What I want to indicate over here is, the
Microsoft Outlook looks around for the SMTP and POP-3 servers through the

I agree that it doesn't sound like an MTU problem. There are often problems
with MTU when DSL, VPNs, tunnels, etc. are used, so people might jump to
that conclusion. But e-mail messages are often very short and would easily
fit into most MTUs even after overhead. To test whether it's an MTU proble
