Hello all members of this list,
I have a kind request to all of you related to deliverability of my
messages. Please help.
Currently I have an issue (again; the previous one from a few months ago was
resolved) with my messages sent to Gmail users - they are put into
recipients' Spam folders. I managed to actually reach someone at Google,
who told me that this is due to huge increase of number of messages sent
from my domain in the last days.
I checked DMARC reports I get from Google and found out that there are
several hundreds of messages coming to Google from the IP address of this
list's server :). So it looks like many recipients of this list use Gmail
addresses and my few recent posts to this list (eg. in the thread about
plaintext) made me look as a spammer to Google :(
It looks like the only way to get me out of this condition is that all of
you who have a Gmail address look in their Spam folder for my messages, and
click "This is not spam" if you find any, to train the Google's AI that my
messages are not spam. That's what I'm asking you.
However, the problem is, you probably get this message in your Spam folder
too, and won't see it :(. So I would like to ask someone who is active on
this list and definitely isn't "spammified" ;) by Google to resend this
message to the list, so you can actually see it.
Would it help if the postfix list used "dmarc mitigation" so that
the From header does not contain your email address:
From: Jaroslaw Rafa via Postfix-Users <postfixmum...@postfix.org>
Reply-To: Jaroslaw Rafa <r...@rafa.eu.org>
"dmarc mitigation" is implemented in mailman(*) and some other list servers.
This may well be the end of the line for the majordomo-based list server.

Mailman would allow you to enable ARC signing [1], which might help aswell.
