-We subsequently use `CHATMAIL_DOMAIN` as a placeholder for your fully qualified

-1. Setup DNS `A` and `AAAA` records for your `CHATMAIL_DOMAIN`. 
-   Verify that DNS is set and SSH root login works:
+    scripts/init.sh 
 
-   ```

-    git clone https://github.com/deltachat/chatmail

+# Chat-mail server development (up until Oct 18th)
+
+## Dovecot goals/steps
+
+- automatic expiry of messages older than M days
+   - also expunge unread messages
+
+- limit: configure max-connections per account
+
+
+## nami: send out rate limit / rspamd
+
+- basic outgoing send rate/limits (depending on "account-rating")
+  use rspamd in a minimal way, check support dkim-signing
+  (including an online test exceeding rate limit)
+
+
+## doveauth questions/futures
+
+- bcrypt-password scheme is slow: require long passwords, use faster hashing
+
+- define user-name and password policies, and implement them
+  (be very restrictive at the beginning, we can relax later)
+
+- password is part of the dictproxy-lookup key, is it safe to use auth-caching?
+
+
+## How to limit creation of accounts?
+
+attack: a 3-line bash script to fill the chatmail db with millions of unused accouts
+
+- make it computationally expensive (somehow try to except our tests from it)
+  1st pass instant onboarding: create userid + cheap password -- if it fails then
+  2nd pass instant onboarding: create userdid + comput. expensive password
+
+- probably also do firewall: limit number of new tcp-connections per IP address per duration
+
+
+## Open/deferred questions
+
+- automatic expiry of users that haven't logged in for N days
+  Is it neccessary?  If all messages are gone, does the existence of
+  an e-mail address bother anybody?
+
+
+## web page for chat-mail servers?
+
+- documentation for users, privacy policy etc.
+  (probably also with provider-messages ...)
+
+
+## online tests (first with plain python/pytest)
+
+- write tests for dovecot login (exists)
+- write tests for postfix logins (exists)
+- write A<>B send/receive tests (exists)
+
+
+## Delta Chat
+
+1. qr code that defines access to a chatmail instance (like mailadm but without http etc.)
+
+2. support for creating username/password and verifying login works
+
+
