Hi.  The above caught my eye.  I have some questions:

1) What if the "formail -D" is done inside a script specified by "formail -s",
   but the -n is also being used?  (I.e., "formail -n -s blah" where "blah"
   is doing a "formail -D".)  Will the ids get corrupted in that case as
   well?
2) Will this "feature" always persist in the future?  I currently use
   "formail -D #### messids -n ### -s" in one of my scripts and I find the -n
   feature great for my particular application.

(As it turns out, I was worrying about #1, and I happened to have found your
mail message in the procmail mail archive.  I was thinking of adding some
lock mechanism to assure that I avert the corruption problem.)

Thanks.

P.S. Feel free to forward this to the entire procmail list if you do not have
     time to address it.
