Best way to determine if simple or extended MAPI was loaded

Question

How can I simply determine if simple or extended MAPI is loaded. Because I want to diable my add in wenn simple MAPI is loaded. I'm working with Add-In Express and Redemption.dll.

Using the Windows "Send To" command actually integrates with SendMail.dll. AFAIK you can't intercept these calls to do something custom, but you can add your own shortcuts in the context menu:
