Surely looks like a mailbox locking problem - two processes writing the same
mailbox file at once. The most likely culprits are a broken pop daemon, or a
broken sendmail setup, or a broken procmail/deliver/whatever-post-sendmail-
processing setup (if you use that), or an interaction between sendmail etc.
and the pop daemon, where they don't agree on a locking scheme (more about
that can be found in the procmail docs).
