 That's what canonical is for, what you describe is done by virtual.

man 5 canonical
[...]
     The canonical mapping affects both message header addresses
     (i.e. addresses that appear inside messages) and message
     envelope addresses (for example, the addresses that are used
     in SMTP protocol commands). Think Sendmail rule set S3, if
     you like.
[...]

man 5 virtual
[...]
     The virtual redirection is applied only to the recipient
     envelope address, and does not affect message headers.
     Think Sendmail rule set S0, if you like. Use canonical(5)
     mapping to rewrite header and envelope addresses in general.
