If the sender already know the capabilities of the recipient, then the sender does not need to use ESMTP/CONNEG. ESMTP/CONNEG is designed for use when the sender does NOT have that information.

There are a number of ways the sender might obtain capabilities before starting this SMTP session.

One example is <http://www.imc.org/draft-ietf-fax-content-negotiation>. Another is, no doubt, via some LDAP-based directory.


You need to decide what the
trade-offs are

By "you" I assume you mean the aggregation of the implementer and the sending system's administrator. There is no need for this specification to dictate that choice.
