Most postfix systems are the final destination for a small number of domain names, including hostnames and machine ip addresses, and sometimes the parent domain name of the hostname, which are called "canonical domains." In postfix they are usually implemented by the local domain address type.

In addition, postfix can be configured as the final destination for any number of additional domain names, which are called hosted because they are not directly associated with machine names. Hosted domain names are usually implemented with virtual_alias_domain address types and virtual_mailbox_domain address types.

In addition, there is a situation: postfix can be configured as an mx standby machine. When the host is down, the standby machine only receives mail and puts it in the queue until the host is restored. This function is implemented by the relay_domain address type.

Finally, postfix can also be configured as a transit machine for sending mail over the network. Only authorized users and clients can use this function, which is implemented by the default_domain address type.

Virtual Domain Name Configuration Example:

1 /etc/postfix/main.cf: 2 virtual_alias_domains = example.com ... other hosted domains... 3 virtual_alias_maps = hash:/etc/postfix/virtual 4 5 /etc/postfix/virtual: 6 postmaster@example.com postmaster 7 info@example.com joe 8 sales@example.com jane 9 # Uncomment entry below to implement a catch-all address10 # @example.com jim11 ... virtual aliases for more domains...
