SPF check

We are looking for an Event Sink using the OnArrival Trigger in IIS SMTP. The event sink should check the SPF result on email received (based on the connecting IP), and add the result into a X-Header. If the SPF record reports SPF Pass, x-header x-xzy-spf:Pass, if result is fail x-header x-xzy-spf:Fail should be included in the Header.

If no result, do not report x-header

Preference for code is Microsoft C# 2005, but not a requirment.

We also want to check connecting IP, and all IP addresses in the received from records from the message headers. (excluding local addresses of or [url removed, login to view] or for presents on a number of blacklists. Blacklists should be specified in an XML file.

If the IP address is listed in one of blacklists, the result should be returned into x-xzy-blacklistname:result

Please feel free to bid for entire project, or either one of the tasks.
