Episode 13: How do I configure sendmail to receive mail for multiple domains?

This can be accomplished by adding the domains you wish to receive mail for in the /etc/mail/local-host-names file. It is important that the sendmail server can resolve these domain names through DNS.


Example:

/etc/mail/local-host-names

# local-host-names - include all aliases for your machine here.
domain1.com
domain2.com
domain3.com
