Cool, seems like what you wanted to implement.

Let me know.

Yes the FSF, would prefer to have the assignement for "GNU software".

Yes, in the long run.  But it does not have to be.  It depends on
the importance of certain piece of GNU software,  for example, for
GNU CC(gcc) the flag ship, every piece is assign/donate to the FSF,
if not it will not get added.   OTOH, GNU grep(2.5) will use libpcre, to do
Perl regex, and libpcre will be distribute with GNU grep but not own(being
the copyright holder) by the FSF.
So it depends on the importance of GNU mailutils, if it becomes important,
a critical component of GNU system.

So yes, we could use cyrus implementation, as a first test.

Being the copyrigh holder gives the FSF standing legal ground to defend
and represent the "work".  However when you assign, the FSF usually
grants you back non-exclusive right to do what-ever you want with it.
