Since you have HT turned off, I presume you're not running an SMP kernel.

This sounds like something's not working quite right but eventually 
times out, creating large delays. I can think of two areas which might 
exhibit this kind of behavior - DNS and database access. My first bet 
would be database.

Are you using a database backend? FC5 uses MySQL5, which is different 
enough from version 4 that it causes problems similar to yours with 
vpopmail.
