I think the following link in master.conf enables smtp. Correct?
smtp      inet  n       -       n       -       -       smtpd -v

I'm trying to get iptables to shutdown. Is iptables -F sufficient to remove any
block it might have?

This is set as follows:
mydestination = $myhostname, localhost.$mydomain rt.$mydomain it.$mydomain

This was commented out.

I don't have this in my config at all. Adding it to the bottom

I'm getting the following in my error_log, but I don't think it's related and so
I'm putting it off till I get this solved.

[Mon Feb  9 22:18:04 2004] [crit]: Trying to check RT::FM::Class rights for an 
unspecified RT::FM::Class (/opt/rt3/lib/RT/Principal_Overlay.pm:355)

I don't think it's related because it's happening at times that don't appear
related to emails. It might just be something with custom fields that I set up.
I'm not sure and haven't really checked.
