As far as I know, internet mail standards do not require anyone
to accept any particular mail, either as final recipient or on behalf
of the final recipient.

The RFC excerpts quoted there, as I read them, say that it is compliant
to send such mail.  They do not say that it is non-compliant to
refuse to accept such mail (although the FAQ itself makes the claim).

(The quoted "must be supported" is in a correction of an omitted
syntax from a list of BNF forms, and not of any requirements of any
particular actions to be taken.)

While I do think it's a BadThing (tm) that they block this way,
I think that this (the non-compliance) argument is not a good one
to use against it.

Cheers,
