Hi, a couple users of my server (ejabberd 2.1.5) report this problem:
"messages from and to users of jabber.ccc.de are dropped silently.
Furthermore, sometimes they are shown to me as online when they are not.
I have successfully contacted them using other accounts and I have no
problems communicating with users of jabber domains other than
jabber.ccc.de."
I grepped my server logs for s2s problems with jabber.ccc.de but I couldn't find any error messages: s2s connections are established successfully; sometimes there are "timeout" messages, but these happen with all servers.
Our DNS SRV records are OK. Can you suggest how can I debug this problem?
