How to set up communication with the outside world for Google Talk on your domain?

Question

gmail

It has its own domain, to which Google mail is attached, it also became necessary to use Google-xmpp. DNS was configured according to the instructions, the necessary SRV records were added, the domain passes this test, with equivalent results for: https://kingant.net/check_xmpp_dns/?h=gmail.com
account, you can write messages to contacts within the domain, but when I try to add to the roster / write a message to other servers, I get:

remote-server-not-found

I understand that Google's vision of xmpp is stubborn, which is closely focused on their services, but is it possible to somehow successfully organize communication with the "outside world" in this case?
UPD : through tests, it turned out that there is a connection between the Google network (that is, between two such domains), but there is no way to other xmpp servers.

Answer 1

Judging by the post on Habré , the “corporation of kindness” did not follow the example of the community and did not support TLS, which led to incompatibility with other XMPP servers, for which this is now mandatory (unless, of course, I am mistaken and understood everything correctly). The only solution here is to use a normal XMPP server, not owned by a large corporation pursuing its own selfish goals.
