Well, IMO this cannot be caused by MailScanner...

What kind of tiemout is this? SMTP timeout?

Which smtp software are you using? Do the log files reveal something
of interest? What does the system load look like?

> Is it possible that Mailscanner is causing that problem?

I don't think so, as MailScanner doesn't do anything on the network
interfaces. It just acts locally...

On which port?
And how do you ping a special port? Or do you mean a switch port?

> Can I do other tests on the server to check this?

A fiend of mine once used some perl scripts to "stress test" a
freshly-installed smtp server - unfortunately I don't know if he
downloaded these scripts somewhere or if they were his own creations.
Maybe you can ask google for something like "mail smtp stress test"...

Christian
