550 Denied due to spam list



This is a fresh unedited install on Red Hat Scalix Ver 11.0.2

Hi!

Denied due to spam list always indicates that the IP address of the SWA server is not listed
in the RELAY accept lines in /var/opt/scalix/??/s/sys/smtpd.cfg.

By default, the Scalix installation will always use the domain name of your server to create
some default rules.

If DNS does not do reverse lookup on IP addresses, the rule won't work. This means you
need to amend it to either include the IP address or fix your DNS so that it does reverse
lookups correctly.

It is strongly advised that you do the latter because a broken DNS may cause problems
further down the line.

Thanks,
Subir

I have forward and reverse DNS setup and it test working ok using dnsstuff.com

this is whats in the file
RELAY accept 127.0.0.1
RELAY accept .mydomain.com
RELAY Log_Reject ALL



do i need to add
RELAY accept host.mydomain.com?

host.mydomain.com is what has the forward and reverse DNS

This looks like you are unable to resolve the IP addresses of the POP clients that are submitting the messages.

The easiest solution is to have your users configure authentication in their POP clients.

Thanks for the help configuring authentication on the client side took care of the issue.
