This might again be a question for the extra group to consider, but if
looking at something like email length, that would apply to both IMAP
and SMTP in a typical situation.

How should things that apply across multiple protocols be addressed in
general, I know that is one of the things mentioned when trying to get
CLIENTID into the working group..

Hey all,

This is my first internet draft I'm sharing here. So I hope you all will
bear with me on this.

I didn't share my initial draft
<https://tools.ietf.org/html/draft-viruthagiri-email-address-length-00>
here. But, Dr. Klensin had given me feedback for that draft off-list.
Turns out I was listing outdated references in the normative references
section among other things.

I have version 1
<https://tools.ietf.org/html/draft-viruthagiri-email-address-length-01>
now. It focuses only on the SMTP extension.

Here is the abstract.

============

https://tools.ietf..org/html/draft-viruthagiri-email-address-length-01
<https://tools.ietf.org/html/draft-viruthagiri-email-address-length-01>

Abstract

    This memo defines an SMTP extension with keyword "EAML" whereby an
    SMTP server can declare that it is capable of handling longer email
    addresses without any local-part or domain-part restriction set by
    RFC 5321.

    EAML stands for "Email Address Maximum Length".

============

This is how it works.

                   S: 220 smtp.example.com <http://smtp.example.com>
ESMTP Ready
                   C: EHLO bob.example.org <http://bob.example.org>
                   S: 250-smtp.example.com <http://250-smtp..example.com

                   S: 250-EXPN
*S: 250-EAML 500*
                   S: 250-PIPELINING
                   S: 250 HELP

The parameter omitted EAML keyword says:

                   [*] No local-part limitation.
                   [*] No domain-part limitation.
                   [*] 254 maximum characters

============

Any kind of feedback will be really helpful.

Thanks
