Introducing similar visual confusion for list-servers the
following will appear:

Yes, this is valid 2822. I wonder what it breaks...
To start, your email client may not accept multiple from addresses.
If you are sending to the list subscribed as sally(_at_)some-school(_dot_)edu,
the list-server may check the wrong from address. If the first
address was guest(_at_)some-hotel(_dot_)com, then subscribing this address may
be problematic. Of course, the list-server application would need to
add the additional from address or be unable to deliver messages with
a first-party mandate. There is also the problem when someone
decides to reply in handling the extra address.
Of course from a privacy standpoint, this exposes the accounts
associated with each provider rather than allowing the sender to use
the preferred email-address. Of course, this also exposes more email-
addresses for spammer who will have no difficulty meeting whatever
requirements erected.
