Hi,
My calls to mail() take a very long time to resolve, so I did a little
investigating. If I try to Telnet to port 25, it takes about 30 seconds for
the SMTP server to respond. Telnet to port 23 on the same address resolves
immediately, as does normal web access (using the same address so I don't
believe DNS is the culprit. Besides, mail() is slow, and that is accessing
the SMTP server locally. What would be taking SMTP so long to respond? Any
configuration parameters I need to look at?
I am using SendMail 8.10.2 on a Cobalt RAQ4.
