@alex @ben @delta I think we're from the same country :blobcatlul: 1. There are dozens of non-public Chatmail relays that are still available. 2. Delta Chat will work with whitelisted email providers while they allow it. (Disable read receipts, don't join large group chats) There's no point in using the said providers as transit relays because they are extremely unreliable with Delta Chat. They not only treat incoming messages as spam, preventing reading them, but also actively block sending messages. It will only make sense if both incoming and outcoming messages to a transit relay are batched and obfuscated to reduce "suspicious" activity - but this also kills real-time messaging.
