Public bug reported:
Please update postfix in saucy to 2.10.2 [1].
It contains changes that seem important for SSL/TLS interoperability, e.g.:
* TLS Interoperability workaround: turn on SHA-2 digests by force. This
improves interoperability with clients and servers that deploy SHA-2 digests
without the required support for TLSv1.2-style digest negotiation.
and
* TLS Interoperability workaround: Debian Exim versions before 4.80-3 may fail
to communicate with Postfix and possibly other MTAs, with the following Exim
SMTP client error message:
TLS error on connection to server-name [server-address]
(gnutls_handshake): The Diffie-Hellman prime sent by the server is not
acceptable (not long enough)
Cheers,
Raoul
