Last time I looked (just now), RFC5321 stated:

Not implemented, yes, and Postfix properly responds with a 502 response
code. Arguably not all that useful when implemented (e.g., as by
Sendmail). But neither "legacy" nor "obsolete" would seem to apply.
Is this reply nitpicky, and/or pedantic? Probably.
Hi,
I think you may be confusing "SHOULD" with "MUST". RFC5321 section 1.3
refers to RFC 2119 for the defintions of these keywords.
RFC2119 states :
1. MUST This word, or the terms "REQUIRED" or "SHALL", mean that the
definition is an absolute requirement of the specification.
3. SHOULD This word, or the adjective "RECOMMENDED", mean that there
may exist valid reasons in particular circumstances to ignore a
particular item, but the full implications must be understood and
carefully weighed before choosing a different course.
Yes, I too am being pedantic/nitpicky ;)
