A couple of days ago I sent out this plea:

Many thanks for those who replied - I have found the culprit but
cannot seem to get it fixed. The correct answer is that my NIS master
was bound to a slave that had lost the plot alias-wise. I rebound my
master to itself and suddenly all was well with the aliases map. I
tried clearing the problem on the particular slave but no matter what
I do it does not seem to want to know about the mail.aliases maps
(only this map - all others are transferred ok). I suppose I should
mention that the real problem child is a Solaris 2 box running a
patched version of the NIS transition kit.

Other suggestions were:

        - I had a -v option in the makedbm command (nope)

Many thanks to these people for their suggestions: (Glenn Satchell - Uniq Professional Services) (Paulo Licio de Geus)
