Redhat mail server - Dovecot & Postfix
 

I've had the mail server running for awhile but when sending mail from workstation it will get a relay error. I've got around this by adding IP's to the main.cf and this works but I need to get the server fixed so that I can add other users and they can send emails without me having to add their IP to the postfix/main.cf file.

Help please.

Use SASL authentication

Thanks Agentsteel. :tiphat:

after running: postconf -a

I get:
cyrus
dovecot

No mention of SASL ...so does this indicate my postfix was not compiled with SASL?
