That was on gentoo.  Sorry didnt think of checking on postfix-3.5.

Just be curious for what reasons we choose to build a software from sources? today it's very convenient to use package management tools to install linux software.

1. Postfix isn't just for Linux.

2. Even for Linux, packaging is variable. e.g. Gentoo's Portage package is mostly used in a build from source mode.

3. Many people want a stable mature base platform (e.g EL7 or even EL6 ) but want to be more current with critical functionality, like the MTA on a production mail server.

4. Some people prioritize the security advantages of bespoke minimized systems with known build conditions over those of a system with builds designed for the broadest possible audience and maintained by an expert team. This is more commonly seen in the BSD world, but it is not infeasible with Linux.
