Autodiscover Email Settings

This service is created to autodiscover your provider email settings.

It provides IMAP/POP/SMTP/LDAP Autodiscover capabilities on Microsoft Outlook/Apple Mail, Autoconfig capabilities for Thunderbird, and Configuration Profiles for iOS/Apple Mail.

A simple support page is also available at the root of the autodiscover domain.

Usage

traefik can proxy your containers on docker, on docker swarm, and on a wide range of orchestrators. You can also achieve this with another proxy like Nginx for instance.

Credits

Inspired from https://github.com/sylvaindumont/autodiscover.xml, but without the few restrictions mentioned in the original project notes and with a simple support page to allow manual setup and iOS profile download.

The original project was inspired from https://github.com/johansmitsnl/docker-email-autodiscover, but with https://github.com/Tiliq/autodiscover.xml instead of https://github.com/gronke/email-autodiscover to allow a much lighter () image based of node on alpine instead of apache on debian ()

Notes

The above autoconfiguration methods assume the following:

• If username does not contain @, full email address will be generated based on domain settings

Links

• Mozilla Autoconfig configuration

• Microsoft Exchange Command Reference

• Apple ConfigurationProfile reference

• DNS SRV Records for LDAP

• Bootstrap, jQuery and Popper.js used for default support page
