Postfix on 2.7.2

[megaconz359]

Hello. Does postfix work on 2.7.2?
After applying https://github.com/marcelloc/Unofficial-pfSense-packages/blob/d34ccc1b15ae342befe48777b014f577355b2453/27_unofficial_packages_list.patch
I don't see anything in the new packages.
How do I install it Unofficial packages?
