d4at.org provides a low-maintenance, resource efficient and
interoperable e-mail service for everyone. What's behind a chatmail is
effectively a normal e-mail address just like any other but optimized
for the usage in chats, especially DeltaChat.
In the Delta Chat account setup
you may tap LOG INTO YOUR E-MAIL ACCOUNT
and fill the two fields like this:
Address: invent a word with
exactly nine
characters
and append @d4at.org to it.
Password: invent at least nine characters.
If the e-mail address is not yet taken, you'll get that account. The first login sets your password.
Un-encrypted messages are blocked to recipients outside d4at.org but setting up contact via QR invite codes allows your messages to pass freely to any outside recipients.
You may send up to 60 messages per minute.
Messages are unconditionally removed 40 days after arriving on the server.
You can store up to 100M messages on the server.
This chatmail provider is run by a small voluntary group of devs and sysadmins, who publically develop chatmail provider setups. Chatmail setups aim to be very low-maintenance, resource efficient and interoperable with any other standards-compliant e-mail service.
