If you submit mail to the server over SMTP (as opposed to Pickup, which
submits using a filesystem hook) from a standard mail client, does the
server successfully send that mail? If so, that indicates (roughly) that
the server is operating correctly at the inbound and outbound SMTP
protocol levels.
The next step is to test using cdoSendUsingPort instead of Pickup. I
prefer to send using Port (i.e. standard SMTP), because it gives you more
resilience (you can switch to an alternate mailserver easily),
scaleability (the application and mailserver don't need to be on the same
box, and error trapping (the application will fault if it can't connect to
the port because the server is down, whereas with Pickup you will not
know if the mailserver itself is responsive).
[To some, some of the above disabilities are seen as advantages: Pickup
will queue your mail regardless of whether the Net is reachable (that's
the "bright side" of Pickup disregarding server state), Pickup will send
mail without the tiny overhead of the TCP/IP stack, etc.]
