Hello,

SPF is configured on public DNS, and you can calculate how is that TXT record gona look like at this site: http://www.spfwizard.net/

As for DKIM, Exchange does not have any built in tools for that, so you will need either 3rd party application (to install on Exchange) or get a 3rd party appliance.

I have not tried this application for DKIM, so I am not sure how it works, but that is the only one I know, for Exchange: https://www.emailarchitect.net/domainkeys/kb/dkim_exchange_2007_2010_2013.aspx

What antispam gateway do you have? Usually those gateways can perform DKIM signing, at least some Symantec and Trend Micro can. Write us a model, so we can check.

At the end, you must have SPF and DKIM to be able to use DMARC.

Regards,
Ivan.

We are using IMSVA gateway.

After adding SPF record, do I need to enable it on our Trend Micro IMSVA gateway ?

I want the gateway to check the IP SMPT gateway for all incoming mail with our company domain. Hence, noboday can spoof our company domain with another SMTP server. Can SPF serve the purpose ? Do I need to enable DKIM / DMARC as well.

Thx
