If you need to assign more than one IP address to a host, use sendmail to set up a virtual host.
Follow the instructions in Virtual Hosting except that in the “Sendmail Configuration” section, do not perform Step 3.b.:
# cd sendmail-VERSION/cf/cf # ./Build mailserver.cf # cp mailserver.cf /etc/mail/sendmail.cf
Instead, use the following commands to set up a virtual host for the Oracle Solaris OS:
# cd /etc/mail/cf/cf # make mailserver.cf # cp mailserver.cf /etc/mail/sendmail.cf
Use the name of the .cf file for the value of mailserver.
For additional information, see the description of virtusertable in /etc/mail/cf/README, and see the sendmail(5) man page to learn how to modify the sendmail.cf configuration file.
