## More information ### Choosing a chatmail address instead of using a random one 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 `@{{config.mail_domain}}` to it. - `Password`: invent at least 10 characters. If the e-mail address is not yet taken, you'll get that account. The first login sets your password. ### Rate and storage limits - Un-encrypted messages are blocked to recipients outside {{config.mail_domain}} but setting up contact via [QR invite codes](https://delta.chat/en/help#howtoe2ee) 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 [100MB messages on the server](https://delta.chat/en/help#what-happens-if-i-turn-on-delete-old-messages-from-server) ### Who are the operators? Which software is running? This chatmail provider is run by a small voluntary group of devs and sysadmins, who [publically develop chatmail provider setups](https://github.com/deltachat/chatmail). Chatmail setups aim to be very low-maintenance, resource efficient and interoperable with any other standards-compliant e-mail service.
