Hello,
I have been following the discussion of the DMARC issues and Mailman's
attempts to live with it. I was wondering if anyone has an "Executive
Summary" of the DMARC issue in a general sense.
The information on the wiki talks about the impact on Mailman, but I need a
generic explanation that can be presented to our CFO. Our management wants to
move our email from an in-house Exchange environment (with Mailman on the side
for mailing lists) to a totally MS365 solution. We have been told that
everything we do with Mailman can be done with Exchange distribution lists,
etc. I know all the reasons this is really a poor statement, but distribution
lists have the same DMARC problem.
I created a test distribution list here. I created local contacts that
forward to my personal gmail.com and icloud.com addresses. I added these and
my work address to the list. Email from gmail and icloud works fine, however
the author address ("From:") carries the original address. When I sent an
email from my yahoo.com account, it was not delivered to gmail. I never saw a
bounce, though, so I don't know who, if anyone, gets notified.
I am hoping that I can make this issue plain at an executive level so we can
get them to stay with a Mailman solution as we "go to the cloud".
Of course if someone says that the current MS365 implementation has addressed
this, then that's a different (unfortunate) story.
