Hi,

I know Xeams supports Domain Keys but I was wondering if one has to setup exchange to send through Xeams as a smart host to sign messages?

Presently emails get sent directly from exchange but come in through Xeams, does exchange need to be changed to send through Xeams?

 

Regards,

James

James,

In order for DKIM to work, out-bound messages MUST go through Xeams. If Exchange sends them out to the Internet, your out-bound email will never have a DKIM signature (unless off course you configure Exchange to sign them).

When in-bound messages come from the Internet to Xeams, it will only validate the existing signature. It will not sign the message.

We strongly recommend you use Xeams for out-bound email as it learns from what goes out and filters get better. Check http://xeams.com/filteroutbound.htm for details.

in regards to this i would love to use xeams as the outbound but we find to many emails get trapped being sent which get triggered on the inbound rules - has this been fixed?

 

do users now get outbound emails that get blocked using inbound rules in their daily report?

 

thanks

0anj,

I assume you are using Xeams in Firewall mode and will forward out-bound messages from your actual server to Xeams, which will then send them out. My answer is based on this assumption.

You need to do 3 things before accepting outbound emails from your actual server:

  • Add the actual server's IP address among the relay list
  • Add the actual server's IP in White Listed IP
  • Add the actual server's IP among the "Trusted IP" for "Auto Learn Sender"

Once this is done, outbound emails will never get blocked.
