[cobalt-users] Slow SMTP (and PHP mail) Response

["Bruce Vander Werf" <brucev@xxxxxxxxxxxxx>]

I am using SendMail 8.10.2 on a Cobalt RAQ4.

Calls to the PHP mail() function locally from our web pages take a very long
time to resolve. Also, if I try to Telnet to port 25 from a remote machine,
it connects immediately, but it takes about 30 seconds for the SMTP server
to respond. Telnet to port 23 resolves immediately, as does normal web
access. I am using the same hostname to connect remotely to SMTP, Telnet,
and the web server.

What is different about SMTP that would cause the delay in response, both
locally and from a remote site? Any configuration parameters I need to look
at?
