So from the irc discussion: two servers, one Ubuntu 10.04, and one Ubuntu 12.04. Both are using postfix. The 12.04 server is running postfix 2.9.6-1~12.04.1.
10.04 is running openssl 0.9.8k-7ubuntu8.20 and 12.04 is running openssl 1.0.1-4ubuntu5.17. The 10.04 is sending mail to the 12.04 server. The 10.04 is getting the following in the log: TLS library problem: 25971:error:14094085:SSL routines:SSL3_READ_BYTES:ccs received early:s3_pkt.c:1146 The 12.04 is getting the following: lost connection after STARTTLS -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1356843 Title: ccs received early To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssl/+bug/1356843/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
