[Mimedefang] Re: calling action_bounce() for viruses

Hey Michael,

I know you've helped me before, and I sent you the 'mtrack' script...

I have complete and tested LDAP lookup code for MIMEDefang which is
multithreaded and both initializes and cleans-up nicely.  It has been tested
on both Exchange 5.5 and Exchange 2000, but the framework should work with
any LDAP compliant user store.  It should work in any part of the filter,
but I use it in filter_recipient().

I'm not sure my company's plan for this code, so I've not generally released
it, but I'm pretty sure it wouldn't be a problem to limit the distribution,
at least initially.  I think the independent feedback would be worth
comparing, in any case.

I can send you my complete 'mimedefang-filter' code, or just the relevant
parts.  I do have some other minor modifications that may or may not be
interesting...
