Virtual Domains

Fri Aug 3 12:14:08 EDT 2007

I had all sorts of problems getting this to work.

I have my firewall running sendmail sending the messages to an internal server 
via lmtp, and then authenticating against postgres. the biggest problems were 
getting the lmtp connection to include the domain of the destination and makeing 
the authentication pass through the domain the user typed in.
