Hello everyone!
I want to make like a mail firewall/gateway that will get all the smtp connections and will filter spam and non-authenticated users.
is there an option that postfix (in the gateway) will forward authentication to my iredmail server and check if the user is exist?

Thank you,
Raz

Install postfix on gateway server, configure it to query/verify accounts against the sql/ldap db on iRedMail server.

Thank you for replying

Will it be possible that the gateway will forward incoming messages to the iredmail server?

Thank you
Raz

Sure. List all relay domains in Postfix parameter "relay_domains =". Of course you can use sql query in this parameter (check iRedMail setting as reference).
