There's a new section in the mimedefang-filter man page with the heading
"INITIALIZATION AND CLEANUP" which says, in part:

"... How-ever, if you are using an embedded Perl interpreter, then anything you call
directly from outside a function definition is executed once only in the parent
process.  Anything in filter_initialize is executed once per slave. If you use any
code that opens a descriptor (for example, a connection to a database server), you
must run that code inside filter_initialize and not directly from the filter,
because the multiplexor closes all open descriptors when it activates a new slave."

If you are creating a new instance of the Net::LDAP object directly in your filter
file (outside of any subroutine), then try creating the filter_initialize sub moving
that initialization inside it.
