mail/postfix and mail/postfix-current need upgrading

[Mark Martinec]

In ports we have:
   mail/postfix-current 2.11.7
   mail/postfix 2.8.0

The version in mail/postfix-current is just barely still supported,
the version in mail/postfix is no longer supported upstream.

Upstream versions are labeled as:
- Postfix 3.2 is an experimental release
- Postfix 3.1 is a stable release
- past stable releases (still supported): 3.0, 2.11, 2.10
- no longer supported stable releases:
     Postfix 2.9 (Final update: October 2015)
     Postfix 2.8 (Final update: February 2015)

The current situation is most unfortunate, as some ports
(like mail/mailman) insist in their dependency on mail/postfix,
which has (among others) no support for internationalized
e-mail addresses, and is no longer supported upstream.

It would be appreciated if both ports were updated.
Preferably mail/postfix to 3.1 and mail/postfix-current to 3.2,
or at least: mail/postfix to 2.11 and mail/postfix-current to 3.1.
