Summary: This draft is on the right track but has open issues, described 
in the review.

Minor Issue: How the new IANA registry is specified

Section 7.2 seems to conflate two things:

- the information that must be provided in a specification
   document that registers new limits

- the information that is to included in the registry itself

ISTM that the registry itself should contain the limit name and a 
reference to the specification document. It might also contain the value 
syntax, or at least an indication if a value is allowed.

The descriptions of semantics, restrictions, and security considerations 
don't lend themselves to inclusion in the registry, but should be 
clearly spelled out in the specification.

Also, the request for the new registry should probably include its exact 
name ("SMTP Server Limits"?), and that it should be included within the 
"MAIL Parameters" protocol registry.

Otherwise IMO this document is in fine shape to move forward.
