although that gives me a level of overhead because I now have a perlscript
calling another perlscript for all messages.
So other than using "save" prior to the pipe to ensure that a copy of mail
is taken is there a way that avoids that?
Like I said before that approach is currently archiving more mail that I'm
comfortable with. Mail only needs to take a backup of these messages
whenever the perlscript has an error.
