Side note:
Agreed on Postfix.
I always think of the Postfix devs as people who take Unix philosophy
seriously. The code does one thing and does it very very well:
It sends and receives mail. It receives it in a way that is hard to hurt the
sender and hard to crash Postfix, and sends it in a way that does not hurt
itself and does not hurt the recipient. Oh, and it natively does a few sanity
checks on the sender, mostly because it's convenient to do it there.
And the config is simplicity itself - define a hostname, domain and a few
other things and the odds are excellent it will work well out of the box as
one of the few setups that 98% of people with mail servers want.
It manages it's own queues beautifully. But, and this makes me sad, it doesn't
really want *me* to manage it's queues. Border controls are hard, and finding
the 1,000 mails some idiot with a Windows bot just sent, and deleting them, is
really hard.
I'm redesigning our mail setup at work,a nd I'm going to do it with exim *and*
Postfix. Exim is the front end I can see, work with, and manage. Exim sends on
to Postfix as fast as it can, and Postfix transparently relays to recipient. I
get best of both worlds :-)
Now let's contrast Postfix with sendmail. No, wait, let's rather not....
