[TUHS] Who is running their own mail server and what do you run?

[Robert Brockway]

I received a private request for info on my Postfix config.  I'm happy to 
post to list.

This is the interesting bit:

Running under Debian 8, soon to be upgraded to Debian 9.

Postgrey is listening on TCP/10023.

As an aside I just saw this in my mail queue:

That is aggressive standards compliance ;)
