It's easier than you think. Or at least, it was for me.
I think the
root of the problem was that I was approaching its
configuration as I did
sendmail, which was a mixture of
trial and error, and walking through a
junkyard with a
blindfold on.
My
advice, for anyone else thinking that qmail is too
difficult, would be to turn off sendmail, and
start qmail. Then worry about the configuration.
Qmail will not relay mail by default, so there's no reason to
fear being an
open relay. If you want to
add/
change/
remove hostnames that qmail will receive mail for, check /var/qmail/control/ to do that. Once done with that, I've found that a ``
killall -1 qmail-send'' works fine for getting it to reload its configuration.
(Yes, I am advocating a somewhat stupid thing--run something, then figure out how it works... But, really, understanding something in theory is much more difficult than understanding something in practice--at least, for me.)
