ha ha ha, that's who you do it. "SMTP clients" use the SMTP
protocol to tcp port 25.

SMTP

Ipswitch?
If there is no initial repsonse to an SMTP call, the timeout could be
quite short, but once an SMTP session is going, the timeouts are much
longer, I bet.

If you're sure that's the case, then shorten the Imail SMTP retry
period to 5 minutes so when Imail does timeout, it will retry fairly
soon, on the assumption that the firewall might just let the mail
through next time, or next time, or next time.
