Hi,
We operate a mailing list on which many members use their Gmail address. In the default settings, this results in a warning and delayed delivery (and maybe marking as spam):
status=deferred (host gmail-smtp-in.l.google.com[74.125.128.27] said: 421-4.7.28 Gmail has detected an unusual rate of unsolicited mail. To protect 421-4.7.28 our users from spam, mail has been temporarily rate limited. For 421-4.7.28 more information, go to 421-4.7.28 https://support.google.com/mail/?p=UnsolicitedRateLimitError to 421 4.7.28 review our Bulk Email Senders Guidelines.
As a preventive measure, it helps to use DMARC mitigation action with “Replace From: with list address” and “ DMARC Mitigate unconditionally ”. But now some users are unhappy with the From header " Username via Test-liste <test@test-liste.org>". They would rather have their email address in it.
Is there a solution with which Google delivers the mailing list messages without complaining, but the sender email address is also in the “From:”?
Thanks Erik
