Comment 3 for bug 1876537

      I further discovered the mailbox in question was malformed, had a space
before the 'From' in the first message. Fixing that, and then deleting the
index file and allowing it to rebuild got customer back in service. I further
found the mailbox got malformed by a users ineptidude, they tried to manually
as in using an editor, move a mail from another box. So that was the cause,
but it would be good for it to handle a corrupted mailbox more gracefully,
perhaps scan to the first good From and go from there.
