One every document attached to an identity with the e-mail address (customer, supplier, employee etc.) can be beyond the memo itself, attach:
for immediate dispatch.
Note concludes with dispatcher and other user defined default termination .
Thats for example. tender, the user can not only send bid as they were printed, but also attach brochures and drawings and MS documents and retrieval of the document immediately see what was sent.
Any problems with surrender to the receiver handled by the deferred mail service.
