I suggest you take a look at the "procmail" package (see comp.sources.misc).
v1.30 is the most recent.  It will take care of all the locking for you.

If you need more information about "procmail", drop me a note (I wrote it :-)

P.S.  I tried to send the mail directly, but your mailer went berzerk.
      If you are interested in the error messages, I still have them.
      I can send them on request, but, be sure to remove your mail filter
      first :-)
