Become superuser or assume an equivalent role.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.
Entries can have the following syntax.
email@example.com firstname.lastname@example.org email@example.com error:nouser No such user here @olddomain.com %firstname.lastname@example.org
Use the user name that was previously assigned with the domain that is newly assigned.

The first entry redirects mail to a new alias. The next entry creates a message when an incorrect alias is used. The last entry redirects all incoming mail from olddomain to newdomain.
Create the database file.
# /usr/sbin/makemap maptype newmap < newmap
Select a database type, such as dbm, btree, or hash.
Use the name of the input file and the first part of the name of the database file. If the dbm database type is selected, then the database files are created by using a .pag and a .dir suffix. For the other two database types, the file name is followed by .db.
