Mail Script won't connect: CDO.Message object Transport failed to connect to the server

A client has a mail script trying to connect to the main smtp server
xxx.xxx.xxx.xxx and if it catches an exception it waits for 10 seconds and
contacts a secondary smtp server at yyy.yyy.yyy.yyy. He is getting errors
from both servers on a regular basis.
