I was looking at postfix and decided to give it a go. But when I apt-get install postfix, it wants to remove exim. So I aborted and did apt-get remove exim to see what its dependancies were, and it would remove mutt, samba and leafnode amongst others. So for the time being I'll give postfix a miss, but lots of people seem to be using it. Does it work alongside mutt leafnode and samba etc?
