avc Dead-Letter? Fedora 10

This is the first Fedora I've come across a files called dead-letter.
I don't use sendmail, exim is installed, if relevant.


Summary:

SELinux is preventing the sendmail from using potentially mislabeled files
(./dead.letter).

Detailed Description:

SELinux has denied sendmail access to potentially mislabeled file(s)
(./dead.letter). This means that SELinux will not allow sendmail to use
these
files. It is common for users to edit files in their home directory or tmp
directories and then move (mv) them to system directories. The problem
is that
the files end up with the wrong file context which confined applications
are not
allowed to access.

Allowing Access:

If you want sendmail to access this files, you need to relabel them using
restorecon -v './dead.letter'. You might want to relabel the entire
directory
using restorecon -R -v './dead.letter'.
