 # Chat Mail server configuration
 
-This repository setups a ready-to-go chatmail instance
-comprised of a minimal setup of the battle-tested 
-[postfix smtp server](https://www.postfix.org) and [dovecot imap server](https://www.dovecot.org).
+This package deploys Postfix and Dovecot servers, including OpenDKIM for DKIM signing.
+
+Postfix uses Dovecot for authentication as described in <https://www.postfix.org/SASL_README.html#server_dovecot>
 
 ## Getting started 
 
-1. prepare your local system:
+prepare:
 
-    scripts/init.sh 
-
-2. set environment variable to the chatmail domain you want to setup:
-
-    export CHATMAIL_DOMAIN=c1.testrun.org   # replace with your host
-
-3. run the deploy of the chat mail instance: 
-
-    scripts/deploy.sh 
+    pip install -e chatmail-infra
 
 
-## Running tests and benchmarks (offline and online) 
+then run with pyinfra command line tool: 
 
-1. Set `CHATMAIL_SSH` so that `ssh root@$CHATMAIL_SSH` allows 
-   to login to the chatmail instance server. 
+    CHATMAIL_DOMAIN=c1.testrun.org pyinfra --ssh-user root c1.testrun.org deploy.py
 
-2. To run local and online tests: 
 
-    scripts/test.sh 
+## Structure (wip)
+```
 
-3. To run benchmarks against your chatmail instance: 
+# package doveauth tool and deploy chatmail server to a envvar-specified ssh-reachable host 
+deploy.py 
 
-    scripts/bench.sh 
+# chatmail pyinfra deploy package 
+chatmail-pyinfra 
+    pyproject.toml
+    chatmail/__init__ ...
 
-## Running tests (offline and online) 
+# doveauth tool used by dovecot's auth mechanism on the host system 
+doveauth
+    README.md
+    pyproject.toml
+    doveauth.py
+    test_doveauth.py
+
+# lmtp server to block (outgoing) unencrypted messages 
+filtermail 
+    README.md
+    pyproject.toml
+    .... 
+
+# online tests (after deploy)
+
+online-tests  # runnable via pytest 
+
+
+
+# scripts for setup/development/deployment 
+
+scripts/
+    init.sh  # create venv/other perequires
+    deploy.sh  # run pyinfra based deploy of everything
+    test.sh # run all local and online tests 
 
 ```

 ## Dovecot/Postfix configuration
 
 ### Ports
@@ -44,16 +64,4 @@ Dovecot listens on ports 143(imap) and 993 (imaps).
 
 ## DNS
 
-For DKIM you must add a DNS entry as found in /etc/opendkim/selector.txt on your chatmail instance.
-The above `scripts/deploy.sh` prints out the DKIM selector and DNS entry you
-need to setup with your DNS provider. 
-
-## Emergency Commands
-
-If you need to stop account creation,
-e.g. because some script is wildly creating accounts,
-just run `touch /tmp/nocreate`.
-You can remove the file
-as soon as the attacker was banned
-by different means.
-
+For DKIM you must add a DNS entry as in /etc/opendkim/selector.txt (where selector is the opendkim_selector configured in the chatmail inventory).
