Security policy stopping mail but cant find what one

[ScottWood]

Hi,

I have an issue where the default domain on my test server has stopped sending mail to any domain, all the other accepted domains are free to do what they like. The NDR is stating that the mail wasnt delivered becuase of security policies, and delivery not authorised, message refused. I havent set any policies to restrict this domain from sending e-mails and everything was functioning correctly, is there anyway of finding out what policiy is blocking the mail?

Thanks

Have you been messing with authentication settings?

Hi,

The only authentication settings I have changed was the outlook anywhere settings, but I would have thought that would have had any bearind on just affecting my default domain..

Thanks

On your SMTP receive connector that receives mail from the Internet, make sure anonymous authentication is enabled.

Hi,

I checked the recieve connector and this is already ticked and enabled.

Thanks
