Qmail isn't a regular package because it's got licence issues.
Also Qmail is lacking in functionality when compared to Postfix, Sendmail, or
probably any other Unix mail server. Qmail is fast and reliable, it's good
for installing for one of those clients who is expected to stuff up Postfix
config files.
For a serious server system it will rapidly become annoying for the
administrator because it just won't do the things you want.
Try spam blocking (both ORBs and header filtering) and address re-writing for
two things that Qmail falls down on.

Postfix does this too.

Being easier to configure than Sendmail is an understatement. Sendmail is
the hardest to configure and Qmail is the easiest.
I doubt that Qmail is any more secure than Postfix. I doubt that it is any
faster.
