First off, you can't do anything about that, yourself.
It is not your problem.

        I have been in touch with a person at Microchip.com who is working
on the problem.  What is happening is that somebody's mailbox at Microchip
has become inoperative for some reason and is now bouncing any incoming
mail from anybody.  Unfortunately, this account is one of the addresses that
receives mail from the piclist.  Every time somebody posts a message, a copy
goes to that dud account and the CC-Mail program at Microchip, after not
being able to deliver the message, politely scans its header for the line
beginning with  From:  After finding that, it sends the bounce to the address
in that line which is the person who sent the message and that is why you
are getting this one.  I will get one of my very own to keep and enjoy
forever a few minutes after I send this one so they are pretty easy to come
by.

        Right now, just ignore them.  The problem is not yours nor is it the
piclist's.  It is just a little bit of erata from the CC-Mail agent at
Microchip.  They will fix it as soon as they figure out what is wrong.
