14 Hello there.
15
16 This is a brief system message to let you know about some upcoming changes to the $HOST service.
17
18 Some of your contacts are on other Jabber/XMPP services that do not support encryption. As part of an initiative to increase the security of the Jabber/XMPP network, this service ($HOST) will be participating in a series of tests to discover the impact of our planned changes, and you may lose the ability to communicate with some of your contacts.
19
20 The test days well be on the following dates: January 4, February 22, March 22 and April 19. On these days we will require that all client and server connections are encrypted. Unless they enable encryption before that, you will be unable to communicate with your contacts that use these services:
21
22 $SERVICES
23
24 Your affected contacts are:
25
26 $CONTACTS
27
28 What can you do? You may tell your contacts to inform their service administrator about their lack of encryption. Your contacts may also switch to a more secure service. A list of public services can be found at https://xmpp.net/directory.php
29
30 For more information about the Jabber/XMPP security initiative that we are participating in, please read the announcement at https://stpeter.im/journal/1496.html
