It is because Postfix is designed as a direct drop in replacement to Sendmail. Me, I've used Postfix for years and prefer it. Something as simple as:

NO_MAILWRAPPER= true NO_SENDMAIL= true

in your /etc/make.conf will preserve your Postfix across buildworlds. I've been doing this for years and have not "lost" a Postfix install yet.

A little RTFM goes a long way. Had you done your reading you would not have had this problem.
