T1113 is used by Mozilla Thunderbird, Evolution, KMail et Kontact.

Outlook and Exchange use their own format, called “autodiscover”.

Plan

We're going to treat autoconfig and autodiscover as dialects and use the same software (static files first, web services to customize reply afterwards). So both will be served by the code from rAUTOCONFIG.

Step 1. Publish a static file
Step 2. Write an intermediary universal format and translators to autoconfig and autodiscover
