The recipient address validation is then done by virtual_alias_maps. /etc/postfix/main.cf: transport_maps = mapping from example.com to smtp:mailhub.example.com relay_domains = example.com relay_recipient_maps = some table that can be empty. virtual_alias_maps = mappings from external-u...@example.com to internal-user(s)@example.comI avoid the need for such empty relay tables, by making all my externally-facing domains (the domains in which users get their primary email addresses) be virtual alias domains. All internal delivery is to "mailbox" domains that are the result of virtual alias rewrites: main.cf: virtual_alias_domains = example.com indexed = ${default_database_type}:${config_directory}/ virtual_alias_maps = ${indexed}virtual transport_maps = ${indexed}transport virtual: u...@example.com u...@mbox-domain.example.com transport: # Mbox domain has MX hosts: mbox-domain.example.com mbox-domain.example.com # Mbox domain has a gateway: # mbox-domain.example.com [mbox-domain.example.com]
