Managing sendmail Services in Oracle^® Solaris 11.4

How to Create a File to Redirect Addresses

You create a keyed map file to redirect addresses from one user and domain to another.

1. Become an administrator.

   For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.4.

2. Create a map input file.

   Create a map input file with the following three entry types:

   • An entry to redirect mail to a new alias

     old-name@newdomain.example.com new-name@newdomain.example.com

   • An entry indicating a message to send when an incorrect alias is used

     old-name@olddomain.example.com    error:nouser No such user here

   • An entry redirecting all incoming mail from the old domain to the new domain

     @olddomain.example.com          %1@newdomain.example.com

   where olddomain.example.com is the domain that was previously assigned and newdomain.example.com is the newly assigned domain.

3. Create the database file.

   # /usr/sbin/makemap map-type new-map < new-map

   map-type

   Select a database type, such as dbm, btree, or hash.

   new-map

   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.
