One customer once asked to set up a forwarding of all email from non-existent addresses in his domain to a specific email address, this is usually called catch-all or luser_relay in postfix.
Let’s say we have an existing email, firstname.lastname@example.org, and we want to redirect all mail from non-existent accounts in the ixnfo.com domain.
This can be done through iRedAdmin-Pro, but in my case there was only free iRedAdmin, then I will show you how to do it through SQL queries.
Let’s connect to the MySQL server:
mysql -u root -p
Let’s select the vmail database:
Let’s add a catch-all account for a specific domain (for example, all email from non-existent addresses of the ixnfo.com domain will be forwarded to email@example.com):
INSERT INTO forwardings (address, forwarding, domain, dest_domain) VALUES ('ixnfo.com', 'firstname.lastname@example.org', 'ixnfo.com', 'example.com');
Let me give you another example, let’s say one mail is created for the domain email@example.com and we want to redirect all emails to it for nonexistent addresses of this domain:
INSERT INTO forwardings (address, forwarding, domain, dest_domain) VALUES ('ixnfo.com', 'firstname.lastname@example.org', 'ixnfo.com', 'ixnfo.com');
Let’s see the added entries in the forwardings table:
SELECT * FROM forwardings;
Here’s an example of deletion:
DELETE from forwardings where forwarding = 'email@example.com' AND id=12;
