Search phpinfo() output for sendmail and smtp.  Make sure sendmail_path is
correct, and that the UID PHP/Apache is running as can execute it.  And watch
sendmail's logs to see what's going on.  /var/log/maillog and the -X switch
to sendmail can be helpful.

In what way?  What do errno and errstr say?

Hmm, odd, maybe:

Yeah, maybe everything is just timing out.  Check DNS responsiveness, rDNS
setup, and /var/log/messages and /var/logl/maillog.  Do you see this behavior
with all protocols? (ie lynx http://google.com)

I'd try to run with a newer kernel, uhh, like 2.4.18.  Or maybe your colo
facility's link is just saturated :)
