I argue strongly in favor of the most precise definition at all times,
i.e., (B). Consider that sendmail might have found that $2 requires
MX delivery Elsewhere. You need to tell Elsewhere where you really
meant for it to go ($2). $1@$2 and $1@Elsewhere are not necessarily
the same person.

Right--(b) is correct, sending to ``user@host''. Why? Many philosophical reasons, but one quite pragmatic one: if your delivery agent gets mail to mail domain ``host'' by dropping it off at the mail relay ``mumble'' (that it found via MX records or some such), then (b) is the only paradigm that allows the server for the machine ``mumble'' to distinguish ``user@host'' from ``user@mumble''.
