Running a mail server for any period of time and you will be offending 
someone's email policy.

There are people out there who still believe that its OK to run an open 
relay and anybody who uses some ORBS type of service is breaking the law.

I have some empathy for the likes of Yahoo, Hotmail/MS and google.

Combined they have something like a billion users.

The most I ever had to deal with was a few thousand mail users and at 
times that made me want to turn off mail and go back to clay tablets.

Of those  millions of users most of them  are amazingly unsophisticated 
so they need to make a number of choices to try and satisfy the largest 
customer base.

After over 35 years of running mail servers I no longer provide nearly 
the feature set that I once did and a few years ago I gave up on running 
any public list servers altogether.

DMARC/DKIM is also more about senders insuring that other mail servers 
do not masquerade as them and that is a sentiment that I can get behind 
with 90+% of bounce back messages being caused by spammers using others 
senders addresses.

This of course can have the side effect of breaking things like mail lists.

Spamming should be a capitol crime.

A few dead spammers hanging in the street could help to clean things up 
quickly.

But that may be just a tad of an over reaction  on my part.
