If you need multiple personalities, that is he preferred approach
(especially considering that there are only three personalities).
If is possible to kludge this with different SMTP clients in master.cf
(smtp-xxx . . . smtp -o myhostname=xxx -o smtp_bind_address=x.x.x.x)
and sender_dependent_transport_maps to select the outgoing smtp-xxx
client. But is a kludge, not a full multi-personality emulation.
