Autoconfiguration for email clients

Question

Email

There is such a thing in Exchange Server - it can configure Outlook clients automatically. For this, a DNS entry is used - Autodiscovery
. Also, if you configure mail clients to connect to global well-known mail servers such as Yandex or Google, just enter your e-mail and password, and the mail server settings in the form of SMTP and IMAP servers will be selected automatically.

how to do it for your server?
how does it even work?

Answer 1

There is this thing for Thunderbird: developer.mozilla.org/en-US/docs/Mozilla/Thunderbird/Autoconfiguration (didn't try it myself)

Answer 2

so read about dnsautodiscovery and configure it the same way.
there is no difference between an internal local domain and a domain that is visible from the world, as is the case with Google, Microsoft and hundreds of other major mail services.
for example, here are a couple of links from the first page of google:
www.computerhouse.com/support/knowledgebase.php?action=displayarticle&id=10
or
hosting.intermedia.net/support/kb/?id=1306
on the microsoft website in machine translation. dns record and xml file on the server
support.microsoft.com/kb/940881/ru
here is another

Answer 3

Thoughtful double googling shows that there is no single standard either in the format of the xml-file with settings, or in the procedure for requesting it.
In particular, an example for TB , as well as, as the Mear user correctly indicated, the procedure for requesting
it . For Outlook, the request procedure can be viewed here
, I will try to twist the options for using SRV records.
