Regarding #2 - There is nothing in Asterisk, at this time, that is able to check the status of a attachment in a message in an external system.  AFAIK.

Sending an email is one thing.  Being able to check the status of an attachment in a specific message, in any one of a variety of systems, is, I think, asking too much.

I don't think most email systems keep track of wether or not an attachment has been read, in any case.
