External Relay

Postby Winaay » Wed Dec 06, 2006 1:29 am

Hi!

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 main.cf file

relayhost = smtp.host.tld

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

smtp.host.tld username:password
