Then you have to define "recognized mailing lists", which might be a
matter for yet another draft.
Wouldn't it be simpler to ask these guys to perform minor changes to their
mailing list software, rather than have to introduce design kluges to work
around them just because they're Yahoo and (whatever)MLM?
So now we're going to ask everyone to rev their DNS servers, their SMTP
servers, their MUAs and their MLMs, in the middle of which everyone is
incompatible with everyone else.
I can really see this working.
There are two possible changes:
1. Yahoo uses a "Mailing List:" header instead of an RFC 2919
"List-ID:" Header. If the PRA algorithm had "List-ID:" between
Sender: and From:, then we could ask mailing lists to use RFC 2919
headers.
It's still asking "nonconforming" mailing lists to conform to
something we want, but at least it's asking them to conform to an
existing standard instead of something we seemingly just made up on
the spot (PRA).
In addition, it will make things easier for their users anyway to
have a List-ID header that more and more MUA's recognize for mail
sorting.
So that requires us to change something, (PRA), and them to
change something (use List-ID).
(It also means sender_agents would work better. :-) )
2. Why is asking mailing lists to use Sender:, (compatible to existing
PRA) in bad form or unlikely to be effective?
From RFC 2822:
|The originator fields indicate the mailbox(es) of the source of the
|message. The "From:" field specifies the author(s) of the message,
|that is, the mailbox(es) of the person(s) or system(s) responsible
|for the writing of the message. The "Sender:" field specifies the
|mailbox of the agent responsible for the actual transmission of the
|message. For example, if a secretary were to send a message for
|another person, the mailbox of the secretary would appear in the
|"Sender:" field and the mailbox of the actual author would appear in
|the "From:" field. If the originator of the message can be indicated
|by a single mailbox and the author and transmitter are identical, the
|"Sender:" field SHOULD NOT be used. Otherwise, both fields SHOULD
|appear.
We'd just be asking mailing lists to do what 2822 says they SHOULD
be doing anyway..
