Postfix Virtual Domain Hosting

The virtual domain support in Postfix is actually quite robust. There are different ways you host virtual domains with Postfix.


 * Canonical versus hosted versus other domains


 * Local files versus network databases
 * Shared domains, UNIX system accounts
 * Postfix virtual ALIAS example: separate domains, UNIX system accounts
 * Postfix virtual MAILBOX example: separate domains, non-UNIX accounts
 * Non-Postfix mailbox store: separate domains, non-UNIX accounts
 * Mail forwarding domains
 * Mailing lists
 * Autoreplies
