I want to translate a domain (foo.myohiovalley.net) to another domain ( myohiovalley.net) such that for all users (xy...@foo.myohiovalley.net) they will be delivered (I'm using virtual_mailbox_domains, etc) as in the target domain (xy...@myohiovalley.net). I thought this would be accomplished by putting "foo.myohiovalley.net" in virtual_alias_domains and mapping " foo.myohiovalley.net" to "myohiovalley.net" in virtual_alias_maps. But that isn't happening as expected. I tried mapping an actual user " xy...@foo.myohiovalley.net" to "xy...@myohiovalley.net" and that actually did work. But I want to do this by domain name only so I don't end up with <number_of_domains> times <number_of_users> mapping entries.
I thought virtual_alias_domains would do this because it is documented with the wording "or domain" but on 2nd reading I guess that is still translating to a u...@domain, where if USER is missing in the map result, it forms an incomplete address (e.g. it doesn't carry over the original username unchanged ... which is what I want to do). Is there a way to just list a set of domains, and what domain to translate only the domain part to, keeping the original username unchanged (at least unchanged in this map)? Note, there will be a LOT of domain names to be translated. The configuration below only shows a couple test domains. command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/lib/postfix data_directory = /var/lib/postfix default_destination_concurrency_limit = 2 default_privs = nobody in_flow_delay = 1s inet_protocols = ipv4, ipv6 local_destination_concurrency_limit = 2 mail_owner = postfix mydomain = myohiovalley.com myhostname = mx.myohiovalley.com mynetworks = 127.0.0.0/8, 172.30.0.0/16,[::1]/128, [fc00::]/48, [fe80::]/48 myorigin = $mydomain proxy_interfaces = REDACTED-OUTSIDE-IP-ADDRESS queue_directory = /var/spool/postfix recipient_delimiter = - smtp_bind_address = 172.30.0.25 smtpd_banner = $myhostname ESMTP - unsolicited bulk or illegal email is prohibited smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_path = private/dovecot-auth smtpd_sasl_type = dovecot smtpd_tls_auth_only = yes smtpd_tls_cert_file = none smtpd_tls_security_level = may soft_bounce = yes unknown_local_recipient_reject_code = 450 virtual_alias_domains = foo.myohiovalley.net, bar.myohiovalley.net virtual_alias_maps = cdb:/etc/postfix/maps/virtual_alias_maps virtual_mailbox_domains = myohiovalley.biz, myohiovalley.com, myohiovalley.info, myohiovalley.net, myohiovalley.org, myohiovalley.us virtual_transport = dovecot File /etc/postfix/maps/virtual_alias_maps that failed: foo.myohiovalley.net myohiovalley.net bar.myohiovalley.net myohiovalley.net File /etc/postfix/maps/virtual_alias_maps that succeeded (but isn't practical to manage for the real cases because the product of the number of users and number of domains will become very large): xy...@foo.myohiovalley.net xy...@myohiovalley.net xy...@bar.myohiovalley.net xy...@myohiovalley.net
