autodiscover is a technique whereby mail client config settings are automatically discovered on setting up a new mail account.

For non-MS (and possibly MS) systems I think this is achieved via a DNS pointer to a server providing the info - see for example:

$ dig @8.8.8.8 autodiscover.fastmail.fm
[...]
;; QUESTION SECTION:
;autodiscover.fastmail.fm. IN A

;; ANSWER SECTION:
autodiscover.fastmail.fm. 300 IN A 103.168.172.65


But I can't find any info on how to set this up outside of MS Exchange but it does seem to have a life beyond Exchange, as in the above example.

Thanks
