Should that be a required error, required to be silently ignored,
or implementation defined?

(The only opinion other than my own that I've heard on this felt
that it should be a required error, so if no one speaks up, that's
the way it'll go.)

I would actually vote for 'implementation defined' (first choice) or
'silently ignored' (2nd). :-)

Why? I was thinking of the LMTP AUTH that can appear in an {S|L}MTP

MAIL FROM=<> AUTH=<user>

this could be mostly useful it it could be referenced to inside the
Sieve scripts.

Since it can be considered part of the envelope, one could use something
like :envelope "auth" "is" "avel" , and in the end use in the Sieve
script the information that a user was authenticated when sending a

So in the end, "auth" should be allowed to be there, apart from 'from'
and 'to'.

OK, you could allow just that one through too, but what if more such
envelope "extensions" appear in the future? A bit difficult but
still. :)
