An alias domain is an alias for a domain that was previously added with the subcommand domainadd. All accounts, aliases and relocated users from the domain will be also available in the alias domain. In the following is to be assumed that example.net is an alias for example.com.
Postfix will not accept erroneously e-mails for email@example.com and bounce them back later to the mostly faked sender. Postfix will immediately reject all e-mails addressed to nonexistent users.
This behavior is ensured as long as you use the recommended database queries in your $config_directory/pgsql-*.cf configuration files.
This subcommand adds the new alias domain (fqdn) to the destination domain that should be aliased.
root@host:~# vmm aliasdomainadd example.net example.com
Use this subcommand if the alias domain fqdn should be removed.
root@host:~# vmm aliasdomaindelete e.g.example.com
This subcommand shows to which domain the alias domain fqdn is assigned to.
root@host:~# vmm adi example.net Alias domain information ------------------------ The alias domain example.net belongs to: * example.com
If the destination of the existing alias domain fqdn should be switched to another destination use this subcommand.
root@host:~# vmm aliasdomainswitch example.name example.org
