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 [1] http://www.postfix.org/announcements/postfix-2.10.2.html ** Affects: postfix (Ubuntu) Importance: Undecided Status: New ** Affects: postfix (Debian) Importance: Undecided Status: New ** Tags: upgrade-software-version ** Also affects: postfix (Debian) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1224029 Title: Please update postfix in saucy to 2.10.2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/postfix/+bug/1224029/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
