[Mimedefang] filter_cleanup question

[Kevin A. McGrail]

So I have a filter_cleanup and I see these errors:

Sep 26 07:54:03 intel1 mimedefang-multiplexor[30156]: Slave 11 stderr: 
Use of uninitialized value in exit at /usr/local/bin/mimedefang.pl line 
5577, <STDIN> line 10.
Sep 26 07:54:03 intel1 mimedefang-multiplexor[30156]: Reap: slave 11 
(pid 5463) exited normally with status 0

 From looking at the code, I think maybe I should have a return status 
on my function so I've added return 0;  If I'm right, I think perhaps 
the man page could be a bit more effusive on that point?
