Re: Debian GNU/Linux as email & DNS server

[Roger Abrahamsson <roger@obbit.se>]

I'd go with postfix...You can set it up as a drop in replacement really 
for sendmail, it has the ability
to use either mysql or ldap as backend and scales well of that I have 
seen. You definitively have to go
with woody or sid, but as long as you run a dedicated server and dont 
have 4000 packages installed it
tend to be pretty stable.. just dont upgrade it everyday, once a week is 
enough, and try and upgrade a test
machine first to see that it dont turn into a veggie.. :-)
It also is easy to set up to use either maildir or mailbox format, and 
you can then pick whatever pop3/imap
server you want..
