RFC1123:

|
| The syntax shown in RFC-821 for the MAIL FROM: command omits

RFC2821 doesn't say it explicitly, but the grammar in S4.1.1.2 implies
that it is a part of the spec, and S6.1 explicitly says that the
"notification MUST be sent using a null reverse path in the envelope."
To me, I think it's pretty clear that a server should support it to conform
to RFC2821 and RFC1123 (which is a clarification on RFC0821).
