[pfx] externel MX question
Hello I have a domain setup in postfix as virtual domains. But MX records for this domain point to external systems currently, such as google workspace. When other users in this postfix system send email to users in this domain, will it be delivered locally? How can I force postfix to deliver messages just following MX records?

[pfx] question on relay_domains
Hi I plan to add a backup mx for the domain. When I checked the doc for "relay_domains" which says, Note: Postfix will not automatically forward mail for domains that list this system as their primary or backup MX host. See the permit_mx_backup restriction in the postconf(5) manual page. I can't understand for this point. can you help?

Can postfix 'recognise' that recipientdomainA, recipientdomainB and recipientdomainC are hosted at the same mail service provider (bigmxprovider.com) so this limiting must be applied automatically?

See the permit_mx_backup restriction in the postconf(5) manual page. This is for domains that are NOT in your relay_domains list. I can't understand for this point. can you help? If you put "permit_mx_backup" into smtpd_recipient_restrictions or smtpd_relay_restrictions, your server will behave as MX backup for any domain. you can restrict this to configure permit_mx_backup_networks in which case your server will behave as backup MX only for domains that point into IP addresses listed there. so, if you have two servers with multiple domains, you can put the primary IP Address into permit_mx_backup_networks and configure permit_mx_backup restriction on the backup server. all domains pointing to your primary will be accept by your secondary.

[pfx] Re: secondary MX server
If I remember correctly, someone mentioned NoListing recently on that list. For this, you *need* a secondary MX, and it is actually your main mail server - the primary MX never accepts mail... Hallo, 1. what's the advantage of this architecture? 2. how to make primary MX not accepting messages?

[pfx] virtual_alias_domains user in dovecot-users
Hello, if a domain is in virtual_alias_domains only, not in the virtual_mailbox_domains. But there is a user on this domain putting in dovecot-users. Can this user get authorized by dovecot SASL and have a mailbox access? (just like the regular domain user.)
