Actually on NetBSD both sendmail and postfix are offered as the
"default" mailers (i.e. their source is in the tree).

Both are considered by The NetBSD Foundation to be under "GPL-like"
copyright though, and both are found in the somewhat optional
"/usr/src/gnu/dist" subdirectory of the source tree.

(Note I don't speak for TNF)

There can be no "assumptions" made when accepting other people's code
for inclusion in a larger project. Either the copyright has to be
explicitly assigned, or it has to be clearly kept separate and its terms
have to be clearly followed (regardless of whether the style of
copyright license is the same as the project it appears within).

Note that in the latter case (i.e. where copyright for contributed work
is not assigned) the larger project is considered under most copyright
laws to be a collective work (and the author's own code within the
project is covered under his own separate copyright license).

In other words it's just as much work to maintain a GPL'ed source
product as it is to maintain one released under any other type of
copyright license! ;-)

(IANAL either, of course)
