Chris,

   The documentation for mimedefang-filter specifically states that if 
you're using Embedded Perl, you *MUST* use filter_initialize to 
initilize variables (such as file descriptors) that need to be seen 
across slaves.

with embedded perl, the (outside of any subroutine) global variables are 
only initialized once on initial startup, and not on a per-slave basis.

check the mimedefang-filter man pages for more specific information.

hope this helps.
