I added my goostapo mail account as a mailing list recipient for this room.
If I get the message, it ought to have the "One Click Unsubscribe" button available, because we generate those headers now, and they are DKIM-signed.
In general, Uncensored seems to be out of the "reject completely" filter and now simply in the "spam" inbox. This is definitely because we started DKIM-signing messages today.
May those responsible at Goolag experience immense suffering as punishment for holding the world's mail hostage.
