Can you add this to the Wiki please? It looks really useful to know.

I helped Mikael test the code a little bit, and I can confirm that it works.

As talked about several weeks ago this is super usefull for all those of us
who suffer from backscatter but for one reason or another cant or wont send
all our outgoing mail via a MailScanner relay.

So kudos to Mikael for coding this sweet addonf or exchange :)

I can only hope it inspires somebody to implement the equivalent functions
as an exchange 2003 event sink.

Best regards
