This repository helps to setup a ready-to-use chatmail server

[postfix smtp](https://www.postfix.org) and [dovecot imap](https://www.dovecot.org) services.

Chatmail accounts are automatically created by a first login,
after which the initially specified password is required for using them.
## Deploying your own chatmail server
## Getting Started deploying your own chatmail instance
We use `chat.example.org` as the chatmail domain in the following steps.
Please substitute it with your own domain.
1. Prepare your local (presumably Linux) system:
1. Install the `cmdeploy` command in a virtualenv
scripts/init.sh
```
git clone https://github.com/deltachat/chatmail
cd chatmail
scripts/initenv.sh
```
2. Setup a domain with `A` and `AAAA` records for your chatmail server.
2. Create chatmail configuration file `chatmail.ini`:
3. Set environment variable to the chatmail domain you want to setup:
```
scripts/cmdeploy init chat.example.org # <-- use your domain
```
export CHATMAIL_DOMAIN=c1.testrun.org # replace with your host
3. Setup first DNS records for your chatmail domain,
according to the hints provided by `cmdeploy init`.
Verify that SSH root login works:
4. Fill in privacy contact data into the `chatmail.ini` file
```
ssh root@chat.example.org # <-- use your domain
```
5. Deploy the chat mail instance to your chatmail server:
4. Deploy to the remote chatmail server:
scripts/deploy.sh
```
scripts/cmdeploy run
```
This script will also show you additional DNS records
which you should configure at your DNS provider
(it can take some time until they are public).
This script remotely sets up packages and configures the chatmail provider.
### Other helpful commands:
6. Run `scripts/generate-dns-zone.sh` and
transfer the generated DNS records at your DNS provider
To check the status of your remotely running chatmail service:
```
scripts/cmdeploy status
### Home page and getting started for users
The `deploy.sh` script deploys
- a default `index.html` along with a QR code that users can click to
create accounts on your chatmail provider,
- a default `info.html` that is linked from the home page,
- a default `policy.html` that is linked from the home page.
All files are generated by the according markdown `.md` file in the `www` directory.
### Refining the web pages
The `scripts/webdev.sh` script supports live development of the chatmail web presence:
```
scripts/init.sh # to locally initialize python virtual environments etc.
scripts/webdev.sh
```
To check whether your DNS records are correct:
- uses the `www/src/page-layout.html` file for producing html documents
from `www/src/*.md` files.
```
scripts/cmdeploy dns
```
- continously builds the web presence reading files from `www/src` directory
and generating html files and copying assets to the `www/build` directory.
To test whether your chatmail service is working correctly:
- Starts a browser window automatically where you can "refresh" as needed.
```
scripts/cmdeploy test
```
Note that this script is not needed for running `scripts/deploy.sh"
which deploys the whole chatmail setup remotely.
The code that generates the web pages is identical
which means that `webdev.sh` gives a pretty good preview.
To measure the performance of your chatmail service:
### Ports
```
scripts/cmdeploy bench
```
Postfix listens on ports 25 (smtp) and 587 (submission) and 465 (submissions).
Dovecot listens on ports 143(imap) and 993 (imaps).
## Overview of this repository
Delta Chat will, however, discover all ports and configurations
automatically by reading the `autoconfig.xml` file from the chatmail instance.
This repository drives the development of chatmail services,
comprised of minimal setups of
- [postfix smtp server](https://www.postfix.org)
- [dovecot imap server](https://www.dovecot.org)
## Emergency Commands to disable automatic account creation
as well as custom services that are integrated with these two:
If you need to stop account creation,
e.g. because some script is wildly creating accounts, run:
touch /etc/chatmail-nocreate
While this file is present, account creation will be blocked.
## Running tests and benchmarks (offline and online)
1. Set `CHATMAIL_SSH` so that `ssh root@$CHATMAIL_SSH` allows
to login to the chatmail instance server.
2. To run local and online tests:
scripts/test.sh
3. To run benchmarks against your chatmail instance:
scripts/bench.sh
## Development Background for chatmail instances
This repository drives the development of "chatmail instances",
comprised of minimal setups of
- [postfix smtp server](https://www.postfix.org)
- [dovecot imap server](https://www.dovecot.org)
as well as two custom services that are integrated with these two:
- `chatmaild/src/chatmaild/doveauth.py` implements
create-on-login account creation semantics and is used
by Dovecot during login authentication and by Postfix
which in turn uses [Dovecot SASL](https://doc.dovecot.org/configuration_manual/authentication/dict/#complete-example-for-authenticating-via-a-unix-socket)
to authenticate users
to send mails for them.
to send mails for them.
- `chatmaild/src/chatmaild/filtermail.py` prevents
unencrypted e-mail from leaving the chatmail service
and is integrated into postfix's outbound mail pipelines.
There is also the `cmdeploy/src/cmdeploy/cmdeploy.py` command line tool
which helps with setting up and managing the chatmail service.
`cmdeploy run` uses [pyinfra-based scripting](https://pyinfra.com/)
in `cmdeploy/src/cmdeploy/__init__.py`
to automatically install all chatmail components on a server.
- `chatmaild/src/chatmaild/filtermail.py` prevents
unencrypted e-mail from leaving the chatmail instance
and is integrated into postfix's outbound mail pipelines.
### Home page and getting started for users
`cmdeploy run` also creates default static Web pages and deploys them
to a nginx web server with:
- a default `index.html` along with a QR code that users can click to
create accounts on your chatmail provider,
- a default `info.html` that is linked from the home page,
- a default `policy.html` that is linked from the home page.
All `.html` files are generated
by the according markdown `.md` file in the `www/src` directory.
### Refining the web pages
```
scripts/cmdeploy webdev
```
This starts a local live development cycle for chatmail Web pages:
- uses the `www/src/page-layout.html` file for producing static
HTML pages from `www/src/*.md` files
- continously builds the web presence reading files from `www/src` directory
and generating html files and copying assets to the `www/build` directory.
- Starts a browser window automatically where you can "refresh" as needed.
## Emergency Commands to disable automatic account creation
If you need to stop account creation,
e.g. because some script is wildly creating accounts,
login to the server with ssh and run:
```
touch /etc/chatmail-nocreate
```
While this file is present, account creation will be blocked.
### Ports
[Postfix](http://www.postfix.org/) listens on ports 25 (smtp) and 587 (submission) and 465 (submissions).
[Dovecot](https://www.dovecot.org/) listens on ports 143 (imap) and 993 (imaps).
[nginx](https://www.nginx.com/) listens on port 443 (https).
[acmetool](https://hlandau.github.io/acmetool/) listens on port 80 (http).
Delta Chat apps will, however, discover all ports and configurations
automatically by reading the [autoconfig XML file](https://www.ietf.org/archive/id/draft-bucksch-autoconfig-00.html) from the chatmail service.

# 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
