The former according to RFC 822; the latter according to SMTP (I do not
know the SMTP RFCs off-hand). Yes, SMTP breaks RFC 822, rewriting broken
mailboxes in an unbroken fashion, in order to ensure that RFC 822 is not
broken :).

Exactly. A Sender header is generated only when this is the case. If what
would be in the Sender header is the same mailbox as is in the From header,
the Sender header should not be generated.
SC> And most well-configured MD lists (cf. a thread on this very list just
SC> a few days ago) use "Reply-To" headers, which, if it exists,
Reply-To is an originator header: only the originator of a message may
create it. If Majordomo is the originator then its mailbox belongs in the
originator (From) header; Majordomo does not do this. If Majordomo is
not the originator then it has no business generating Reply-To headers.
Either way, Majordomo breaks RFC 822 if a Reply-To header is generated.
