I agree. Thank you for doing so.
3 Scenarios Involving Mailing Lists
Whilst this section covers many interesting cases, it is not clear
that all the possible scenarios have been addressed.
I therefore suggest classifying systems against three orthogonal axes:
1. Does it have a UTF8 submission address?
2. Does it accept subscriptions to UTF8 addresses?
3. Does it accept UTF8SMTP messages?
In principle, that gives 8 different kinds of mailing lists, though
not all of them are sensible. But the requirements can be discussed
separately for each of those axes.
Sounds reasonable.
1. If it has a UTF8 submission address, it SHOULD publish an ASCII
alt-address as well. Clearly, it needs to sit behind a
UTF8SMTP-enabled MDA. If it also intends to use a UTF8 Return-Path,
that too should have an ASCII alt-address, and it will need a
UTF8SMTP-enabled MSA with at least the capability to accept that
address in a MAIL FROM. There are also implications for the List-*
headers (see below).
I'm inclined to think that even lists which use a UTF8 submission
address should use an ASCII return-path. Seems much safer. I'd like to
know what others think of this, though.
