The word canonical occurs exactly once in RFC 2822. This occurrence
is not in the context you are talking about.
The RFC does not appear to distinguish between mailbox specifications
in the Sender header and in the From header, w.r.t. validity. Hence,
if you require FQDN in the Sender header because of validity, then you
also require FQDN in the From header because of validity. It is very
easy to show that there are thousands of people where the FQDN does
not lead to a very valid mailbox spec. Hence, the FQDN requirement is
not useful in practice.
And it is not present in the RFC 2822, as far as I can see!
Hm. Now I looked in RFC 2821, and there I can't see the FQDN
requirement, either. So where do you get it from?
