If you aren't doing a complete login/logout sequence and possibly even 
pulling down a message you aren't performing an accurate health check to 
begin with.  We don't use nagios but I'd be surprised if those scripts 
don't optionally take a username and password.

Same here.  We use LVS with surealived and LUA scripting to do a 
complete login/logout cycle as part of the health check.  Even the 
ancient Alteon's had similar functionality (and supported common 
protocols like pop and imap out of the box.)
