OK - that looks like it will do the trick. However, it still won't  give me
the same efficiency as the Communigate method. If I need to send, say, 10000
mails, my Perl program must incur the overhead of 10000 executions of
postdrop, as against creating 10000 files. Postdrop is going to do the 10000
file creations anyway, so from my POV the 10000 calls of postdrop are pure
overhead.
