Hi,
a few weeks ago the GMX mail servers stopped sending mails to my server.
The GMX mailer daemon writes:
A message that you sent could not be delivered to one or more of
its recipients. This is a permanent error. The following address(es)
failed:

remote MX does not support STARTTLS
Thing is that my mail server does support STARTTLS and also advertises
this which I verify in the Exim debug log and was also record with tshark:

mail.eyrich-net.org: lost input connection
Has something like that happened to you in the past or can you reproduce
it on my server?
BTW: Yes, mails from other systems arrive without problems. So that
looks like a general GMX error to me. But GMX is a quite large provider
here in Germany and the problem persists since begin of September
now—shouldn’t somebody have noticed that?
Since I also wasn't able to contact the GMX postmaster I’m asking you
for ideas.
Regards,
Christian
