While I also pine for the simpler days when you could just make a mailing
list out of a mail alias, the reality today is that there are a lot of
facilities built to deter spammers that create a roadblock for legitimate
email admins to work through. The main ones we are dealing with here are
meant to deter email forgery. This happens when a spammer forges *your *email
as the purported source of their abuse. Thus, the better email servers all
implement features like DKIM, DMARC, and SPF, which are meant to stop such
forgery. The problem is that when a mailing list server relays your
message, *it *is seen as the forger. So, there is significant mangling of
headers that has to go on for a mailing list to operate properly today. The
admin is working through this.
