Dear Mailman3.com users! We observe a growth of deferred messages sent to Gmail at the moment.
If you noticed delays in the delivery of your messages to Gmail users, please ensure you set the DMARC mitigation setting for your lists, and if you have DMARC mitigation set to NOT unconditionally, put the following regexp into the "DMARC Addresses" field of the same page: ^.*@gmail\.com$ With this setting, all the messages to Gmail will be DMARC-mitigated (even though Gmail publishes the DMARC DNS record with policy "p=none" which tells Mailman to ignore it). Sincerely, New IT
