How are you calling your outbound mail functions? via SMTP or 'sendmail' ?

The one thing that comes to mind for me is, if you're using SMTP and 
you're using an MTA which has something similar to Sendmail's GreetPause 
feature, and you don't have it configured properly, you could be causing 
yourself unnecessary delays.

check your etc/RT_SiteConfig or etc/RT_Config files to see what your 
outbound mail settings are, and then AS THE USER THAT RUNS HTTPD, try to 
simulate the outbound mail process from the command line to see if that 
gives you any clues.  Also, check your mail and httpd log files to see 
if there are any clues there.

hope this helps.
