Thanks.  Please notice that the mailbox is not empty - its size is 1
byte, which is wrong.  Please empty it with the following command:

	> /var/spool/mail/jrm

(that is, redirect the "output" of "nothing" to it).  Then make sure
that its size is 0.

It sounds like you have local deliveries setup incorrectly, resulting in
mailbox corruption.  Maybe your local deliveries and popa3d are not
configured to follow the same locking convention.  It may be
time-consuming to debug this problem via this mailing list.  If you
like, I can debug and fix the problem operating on your server over SSH,
provided that you compensate for my time.  Please contact me via private
e-mail if you're interested.

If this server does nothing more than e-mail, you might consider
re-installing it with Openwall GNU/*/Linux (Owl) - which has correctly
configured Postfix and popa3d available for use out of the box.
