Looking again it it is quite possible that I simply didn't
get what you were trying to say.
The fact that there are systems, you might wish to label them as legacy
systems, but I will venture they are still active and currently
supported systems, that don't expect to deal or work or make sure it is
consistent with a multiple From: address concept.
To presume that this is a supported concept across the board from MTA,
to MUAs, across multiple mail networks, etc, etc, is simply not the reality.
For a quick example, right now, using the Thunderbird MUA, it does not
allow me to create a multiple from reply or new message.
From a presentation standard, the TBird MUA presents only the 1st address.
I have not checked the Outlook MUA, but it will present all the From:
lines as one.
But overall, I will not be surprise to see incompatibility because
historically, in the annals of electronic mail systems, not just x822,
it is an odd-ball consideration. It is a special case for mail writing
software to support this concept.
You can not expect this to survive across the board.
For our hosting system, which supports both x822 and raw proprietary
transformation formats, maybe operations use the transformation as a
legacy interface and as well as security filter (no HTMLs). I can tell
you multiple From: addresses will not survive.
For legacy networking concepts, which we still have many customers
using, QWK systems do not support it and FIDONET systems do not support
it. So the concept is a non-priority for these customers.
All our presentation devices, Online HTML, Off-loaded GUI, Online
Console Text, etc, do not expect Multiple From: lines.
Are we alone? I doubt it.
Now, at the SMTP level, it would be something we need to take account
for DKIM/SSP for verification purposes. But thats it. Users who are
concern will 100% RFC x822/MIME support, will turn on their "Preserve
Mime" user option and our system will store the message as it, no
transformation. So its not a big deal, and I doubt the multiple From:
potential will ever be a big deal to anyone because are extremely
high, this will reflect malicious mail more so than legitimate mail, and
if its legitimate then it will be correctly DKIM signed.
