Okay.
This is, after all, just like llvm-devel flavor of my earlier email.
It's time to pass the baton to people-familiar-with-flavor@FreeBSD :)

Pkg will similarly not see postfix-sqlite-3.7.3_1,1 as a viable dependency due to the pkgname mismatch, try to install postfix, and fail on the conflict.

Since all flavors of postfix install that program, all of them meet it. But now I can't specify a version restriction.

For python, Mk/bsd.default-versions.mk is the way to fix the FLAVOR, but is there any way to know the FLAVOR of postfix or other pre-installed stuff?
I can only think of the following methods.
POSTFIX_PKGNAME!= pkg query %n mail/postfix || echo postfix-sqlite # use flavor @sqlite
.if empty(POSTFIX_PKGNAME:Mpostfix-*)
RUN_DEPENDS+= postfix>0:mail/postfix
.else
RUN_DEPENDS+= ${POSTFIX_PKGNAME}>0:mail/postfix@${POSTFIX_PKGNAME:S/postfix-//}
.endif
If that fails, it need to use other methods.
Using the same flavors as postfix, OPTIONS to choose postfix flavor or split into m@ster and sl@ve...
