RE: Postfix under Debian 3.1 not working
Just 
guessing, try command> hostname
 
was 
this working before hand? Or is this a new install?
 
what's 
in your /etc/hosts ,  /etc/hostname and do you have a  
/etc/mailhostname  ?
 
The 
gethostbyname should be able to resolve your 
computer's hostname.
 
What 
about doing some nslookups. Do they work? nslookup localhost or nslookup 
hostname

  Success
