service providers use names like mail.example.com, smtp.example.com,
imap.example.com etc. Would it be useful for this document to
encourge the use of specific hostname parts for specific functions?
(Hostname part is probably the wron term, I mean the smtp, imap,
mail parts of those names)
I agree with you that the answer is "no".  I don't think we want to
create some sort of reserved word list within the domain name itself.
But why do you ask?  Do you perceive such a need?
I wasn't thinking of a reserved word list, but more like a
recommendation to mail service deployments, CAs and MUAs to
say please do use e.g. smtp.example.com for submission (and
not mail.example.com) and to please use imap.example.com
etc. The possible benefit would I think be an increase in
the success rate when MUAs guess those names starting from
a mail address, for cases where the SRV thing hasn't been
done. But, I still think the answer is no;-)
IMHO, this is something for the to-be-written mail service discovery document, which is not this spec.
