>Description:
When build mail/postfix (current version 2.10.2) package from source against Berkeley DB ver 6, then build just fails with postfix source code error Unknown Berkeley DB version.
>How-To-Repeat:
change default Berkeley DB version to 6 in make.conf
echo "WITH_BDB_VER=6" >> /etc/make.conf

make -C /usr/ports/mail/postfix/Makefile install clean
>Fix:
There is two fix in my mind:

1. Wait when BDB 6 support officially become available in postfix and till that check default BDB version in mail/postfix port Makefile and if its greater than 5 then give error.

2. Add little patch to postfix port to support unofficially bdb ver 6:
