An MTA (Mail Transport Agent, or "SMTP server") has no bearing on the
client-side "attachment" structure. An MTA simply passes the "attachment" in
the DATA portion of the SMTP dialog.
The client arranges the DATA portion of the exchange to conform to MIME
standards; it has nothing to do with the server.

RFC 2821 is the animal. The only relevant verb is 'data'.
Everything else is handled by 'internal' structuring of the 'data'
segment.
as regards the 'internal structuring', see RFCs 2045-2049, 2184, 2231, 2646,
3798, 4288, 4289, for starters.
