OS to replace FreeBSD

[Paul]

You are free to use Postfix , I was not mocking Postfix users I was justifying the use of Sendmail as the default mail server in Bsd. 

The person who created the virus was Dr. Robert T. Morris, MIT Professor...

Maybe you should upgrade to their commercial version if you think that the open source is not serving you massively enough. They are serving more than 1/2 of the Fortune 500 companies maybe even your favorite Mike Dell but poor Jerry doesn’t like it... https://www.proofpoint.com/us/customer-stories <https://www.proofpoint.com/us/customer-stories>

Some 20+ years back it was fresh in everyone's memory that the worm used sendmail bug and did a lot of damage on the internet (everybody remembers the name of the guy who wrote the worm, right?). So, back then when I was deciding what SMTP server I run, here were the decisive factors:

Most notably: the daemon that is listening to the SMTP (SMTPS) port(s) and the only component that is exposed to external world is very simple short code that just communicates, checks what's necessary and accepts message for further processing. It is very hard to have overlooked bugs in simple short program. And that daemon runs as regular user. Sendmail (at that time at least) was one huge program (hence it is much harder to debug and make it clean) that did everything, including listening to internet, and the daemon runs as user root.

And I can (to an extent) edit sendmail's "low level" config files directly (not only config file from which these are "compiled"), which loosely compares to editing assembly code vs high level programming language code ;-)  Yet, I still prefer postfix's plain ASCII config files.
