    Default External Relay

    Thanks for Zimbra, this has made our messaging system look good. Ours is a very small org with around 25 people. We have our mail server hosted with some service provider. We are fetching the mails vis pop3 from our external mail server. The outgoing mails are being relayed directly from zimbra. We are facing the issue at the point since we have an ADSL link and the ip gets assigned automatically. The IP assigned by our ISP are already made it to the Black list of many RBL servers. This causes lot of mails to bounce back. We are thinking of relaying it to our external server. But the problem is our external server receives mails only after Authentication.

    How do i configure Authentication before relaying it to our external server

    Hope i will get a solution f or this.

    add the following to the bottom of the postfix file
    relayhost =
    smtp_sasl_auth_enable = yes
    smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
    smtp_sasl_security_options =

    this is what the /etc/postfix/sasl_passwd file looks like
    cat /etc/postfix/sasl_passwd usernameassword
