Hello there,

A DKIM record is another measure that can prevent spoofing and improve mail reliability. You can use any online tool to generate the key for you.

We do have an article on How To Install and Configure DKIM with Postfix on Debian Wheezy

Once created you can use a DKIM checker tool like the one provided from mxtoolbox or mail-tester and check whether the generated key is valid.

Hope that this helps! Regards, Alex
