I was thinking that just the domain needs to match. You'll get the

vaguely remember being an example case in one of the messaging RFCs
(can't remember which now).
RFC 2822, Appendix A.1.
The author's domain can be different from the sender's domain.
SM,
You're reading this a little out of context. This isn't about whether
the message is legal or not, it's for determining whether the Sender
address can be used as a "tie breaker"to select among multiple From
addresses to determine which domain should be used for an SSP lookup.
I'm thinking that if we want to be thorough in handling this case (and
the fact that there have been ~110 messages on this thread, despite the
fact that it's an exceedingly rare corner case, seems to suggest that we
do) then SSP lookups should be performed on the domain(s) of all
address(es) in the From header field, excluding those addresses for
which there is a valid Author Signature.
