Indeed, you are correct -- according to section 3.2.3 in RFC 5322,
the at ("@") symbol counts as a "special" character that's
categorized seprarately from "atext," and an example in Appendix A
demonstrates quoting when a special character is present:
RFC 5322 :: Internet Message Format
https://datatracker.ietf.org/doc/html/rfc5322#section-3.2.3
Thanks for pointing out my PEBCAK* error -- I somehow got the eMail
address included in the atext Atom of the "From:" field. :D
Sorry about that.
