Hi All
We have a requirement where we need to reject senders if they are not present in our ldap virtual domains. Scenario => postfix 2.5 with openLDAP (with various virtual domains) Problem Description => Unknown senders (mail ids that are not present in LDAP) are able to send mails to recipients in these domains. (Relaying is blocked of course for external domains) Requirements => A user (not present in LDAP) should be blocked from sending mails. Challege => We cannot apply check_sender_access based on LDAP as that would lead genuine mails from external domains also being rejected CAn you suggest a parameter which can accomplish this, or we need to write our own policy for this ?
