Does anyone have a recommendation on how to send email within DNN without the slow delay caused by SendEmail?  I tried using the Bulk method, however for sending a single email it's just as slow.  I'm looking to do something Async in a fire and forget fashion.

How I got around this:

I had the SendEmail stubbed out anyway, so I simply INSERT the To, BCC, Subject and Body into a table and run a scheduled task in the background.  This means the email seems to go right away, however it is actually being delivered by a background process.  As a bonus it's logging all emails sent via my code from the site.  I don't want to change core at this time, but perhaps in the future having this done by either a service or scheduled task would be an optimal scenario.

The real issue was the time taking to Send if it was done as part of a user request.  If I use the Bulk method with a user it takes just as long to send 1 email async as with the non async and the user experience runs into a brick wall.  By sending on a scheduled task from the database it doesn't affect the user experience and can take as long as it needs to by using the serialized non-async method.  Each email is unique.
