I feel like everyone has moved on from qmail to postfix; I wonder who is still using qmail. I was a huge qmail fan back in the mid '90s, it was a breath of fresh air in comparison to sendmail. But by the 2000s it was feeling largely abandoned, had a lot of hoops you had to jump through, and Postfix was on the scene and had none of those disadvantages.

The last time I used qmail, it was quite a pain to collect up all the required patches and build, just to make a reliable MTA. I'm thinking things like the TCP DNS patch so you could send e-mail to AOL.

I realize netqmail came along later to try to fix this. I guess I had just assumed that everyone had moved on to postfix like I had.
