Email addresses will not contain the @ character in the local part,
only POP3/IMAP login names (and /var/mail/MAILBOXNAME).
The "domain" part of the login name won't be DNS domain names,
just fictional names, solely for namespace separation.

We will have an aliases view with the format:
email_address: target1, target2, ...
where targetN may be a local user or an email address.

Should we use the following format?

postmaster@???: postmaster@our_main.domain
user@???: "user@name_space.domain"@localhost
