# MailAutoConf - a simple, configurable autodiscover/autoconfig service for distributed and self-hosted services.  

## What is MailAutoConf?
MailAutoConf is autodiscover/autoconfig web server for self-hosted mail services
which do not have their own autodiscover service.

## What does MailAutoConf do?
MailAutoConf is currently in _very_early stages, but it does generate valid
autoconfig XML files (/mail/config-v1.1.xml) compatible with many mail clients
i.e. Thunderbird, Evolution, etc.  
Theoretically, anything that can read the standard autoconfig XML file -
https://wiki.mozilla.org/Thunderbird:Autoconfiguration:ConfigFileFormat, should
be able to auto-configure using this service.

## Installation
The container file includes set up for an apache webserver to run the application.
You will need to supply a volume for the configuration file and port forwarding.
```
podman run -dt \
  --name mailautoconf \
  -v ./config:/var/www/html/config \
  -p 8010:80 \
  pswilde/automailconf
```
You will need a reverse proxy server to publish to the outside world and handle SSL encryption.  
For example, in nginx:
```
server {
  listen                443 ssl;
  server_name           autoconfig.example.com;
  ssl_certificate       /path/to/certificate.file;
  ssl_certificate_key   /path/to/certificate.key
  location / {
    proxy_set_header    X-Forwarded-Host $host:$server_port;
    proxy_set_header    X-Forwarded-Server $host;
    proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass          http://localhost:8010/;
    proxy_redirect      http://localhsot:8010/ /;
    proxy_read_timeout  60s;
  }
}
```  
First run will create sample.ini files in the config directory. Copy these to config.ini and services.ini and configure them to your needs.  

MailAutoConf will handle all the URLs it's able to deal with, i.e. /mail/config-v1.1.xml, /Autodiscover/Autodiscover.xml automatically.  

## DNS config
You will need to configure DNS records for your domain.  
I would recommend setting up an A record for autoconfig.your.domain to point
directly to your MailAutoConf's instance which will work for Thunderbird and
Evolution clients.
Then, if Outlook Autodiscover is required (currently not implemented), configure
a SRV record to redirect to the autoconfig.your.domain A record. i.e.
```         
Type                                TTL  P  M  Port Target
SRV _autodiscover._tcp.your.domain  3600 10 10 443  autoconfig.your.domain

## Future plans
MailAutoConf is currently in _very_ early stages, with a _very_ limited set of features.
My hope for MailAutoConf is to run as an autoconfig service which provides Calendar and AddressBook locations as well.
Calendar and AddressBook is in the autoconfig XML documentation, but currently not implemented. MailAutoConf can generate the correct information for Calendar and AddressBook into the autoconfig XML file, though no clients currently use it.

Things I'd like MailAutoConf to do:
- [*] /mail/config-v1.1.xml file for Thunderbird and Evolution mail clients.
- [ ] Autodiscover.xml for Outlook clients - currently does generate, but untested.
- [ ] Autodiscover.json for more modern Outlook clients - this is currently undocumented. I have implemented some features of it but it is currently not working.
- [ ] Calendars and Address Book - does generate into mail/config-v1.1.xml, but no actual clients support it yet.
- [ ] Additional, custom services. For example, Nextcloud - instead of having to type in your Nextcloud instance URL, you can just enter your email address associated with you Nextcloud account and it looks up the URL from autoconfig - wouldn't that be nice?
- [ ] Probably loads of stuff I haven't thought of yet.


## When will it be ready for production?
Well, not yet. Though it does sort of work already.
I'm working on this ultimately for my own use for my own small business. I'm hoping once it's good enough I could deploy the set up to my businesses customers and ultimately get them away from a Microsoft Exchange based environment. There's a long way to go for that right now though.  

If you feel you may be able to help, or ideas on features and their implementation, notice any bugs, or just want to say hi. Please do so and submit a pull request if required.

Thanks for reading!
