Auto-discovery for Mobile Devices (ActiveSync)

Axigen Documentation

The ActiveSync features built into Axigen aim to provide data and option setting synchronization between the email service and a user handset compatible with the ActiveSync protocol. The Axigen implementation of ActiveSync is based on the standards used by the Exchange® ActiveSync® protocol.

The ActiveSync connection uses the WebMail service on the server side. The Auto-discovery feature can be used in order to simplify the client configuration process for mobile devices. The user can specify only the email address and the password for accessing her or his Axigen account.

In your DNS server, configure an entry with the name autodiscover.youremaildomain.tld, such as:

The ActiveSync service will connect to the WebMail Listener that listens on port 443 (default HTTPS listener).

The Auto-discovery service will provide your mail server settings and you will only need to tap on "Next".

The request is traceable in everything.txt (log level set to "Protocol Communication") and should be similar to:
