Mohlo by Vám pomoci pouzivat mechanismus virtualnich uzivatelu (sendmail
8.8.*, konkretne nejnovejsi 8.8.5). Cituji z ./cf/README:

virtusertable   A domain-specific form of aliasing, allowing multiple
                virtual domains to be hosted on one machine.  For example,
                if the virtuser table contained:

                        info at foo.com    foo-info
                        info at bar.com    bar-info
                        @baz.org        jane at elsewhere.net

                then mail addressed to info at foo.com will be sent to the
                address foo-info, mail addressed to info at bar.com will be
                delivered to bar-info, and mail addressed to anyone at
                baz.org will be sent to jane at elsewhere.net.  All the host
                names on the left hand side (foo.com, bar.com, and baz.org)
                must be in $=w.  The default map definition is:

                        hash -o /etc/virtusertable

                A new definition can be specified as the second argument of
                the FEATURE macro.

Pro inverzni mapovani pri odesilani je mozno pouzit tabulku ,,generics``.
Opet cituji z tehoz zdroje: 

genericstable   This feature will cause certain addresses originating in the
                local domain or a domain listed in $=G to be looked up in a
                map and turned into another ("generic") form, which can change
                both the domain name and the user name.  This is similar to
                the userdb functionality.  The same types of addresses as for
                masquerading are looked up, i.e. only header sender addresses
                unless the allmasquerade and/or masquerade_envelope features
                are given.  The addresses must be in the list of names given
                by the macros GENERICS_DOMAIN or GENERICS_DOMAIN_FILE
                (analogously to MASQUERADE_DOMAIN and MASQUERADE_DOMAIN_FILE,
                see below).

                The argument of FEATURE(genericstable) may be the map
                defintion; the default map definition is:

                        hash -o /etc/genericstable

                The key for this table is either the full address or the
                unqualified username (the former is tried first); the
                value is the new user address.  If the new user address does
                not include a domain, $j is used.
