Postfix stable release 2.9.2 is available.

This release adds support to turn off the TLSv1.1 and TLSv1.2 protocols. Introduced with OpenSSL version 1.0.1, these protocols are known to cause inter-operability problems, for example with some hotmail services.

This is a real issue, since mail just stays in the queue, because the other side drops dead.

This is not a wishlist bug:

a) Wietse doesn't release patch releases to Postfix unless necessary
    lists for severity "medium":
    "A bug that has a moderate impact on a core application"
   postfix is a core application and this issue renders TLS inoperational for a multitude of sites (when trying to send mail there)

I agree it's not wishlist. I'll try and look at getting the update tested soon.

Quantal has 2.9.3 so marking fix released.

Scott/Lamont - are either of you working on an SRU for precise?

I've started looking at it and I think this is perfect for the microversion
release exception we have for postfix. I continue to have trouble getting the
QR tests to pass on either the current package or the new ones. If someone
could run those and let me know they're OK, I'll prepare an upload.
