We have a service that allows users to send a formatted JSON request to the gateway to send an email using the 'Send Email Alert' assertion. We're getting requests from clients to include attachments. The email client of the standard assertion does not include a place for attachments nor am I sure where we would store or address such documents if it did.
It would seem to me, however, that if a message body was MIME encoded with an included attachment it could be referred to via a context variable and sent via the assertion. Unfortunately, I would have no idea how to do such a thing.
Has anybody done any such thing or have any other ideas that might work.
