Bug#343085: exim4: Exim SMTP_AUTH hangs since today for important german provider (1und1)

[Dr. Jürgen Pfennig]

Package: exim4
Version: 4.54-2
Severity: normal

Since today "exim4 -qf -v" showed that the connection hangs after
TLSSTART. The thing has worked well for several months before. An update
from 4.50 (sarge) to 4.54 (test) to not solve the problem. After
disabling TLS I can send mail again.

(1) Assuming that it's a provide side bug - Please improve documentation on
    how to disable TLS and using PLAIN TEXT
(2) If it's not a provider side bug - could it be fixed?

Additional info: my exim log contained occasional entries like:

2005-12-06 21:29:09 1EjicG-0006au-Px TLS error on connection to
  authmailonline.kundenserver.de [212.227.15.164] (gnutls_handshake):
  A record packet with illegal version was received.

Thanks, Juergen
