How to set up DKIM key

Any messages sent from our smtp servers are signed with DKIM signature using servermx.com keys.
You do not need to set any values in your DNS nor creating any keys.
When a custom dkim key is required then the user has to add in his DNS a dedicated public key generated for his domain name.
This public key that has to be added in the DNS as the following TXT record

 

for example:

-----BEGIN PUBLIC KEY-----
MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDb6VDQw8QhpwAhZwoFCm4fIh4q
x4BgrFGN+vlcBGj+vVYPij8ZuNIav2FuR8vo2YMDIZ+fAGuEXHQep/8+pVcITZdX
+hsnItQXyojQ9pUl0XvHvLoSdsxBjYCOMFiZmjS/UqZbYrVOm3Cc3k2+wuoPh6U9
LyYhJS9iRNg+jaZ4tQIDAQAB
-----END PUBLIC KEY-----

 

DNS txt record:

servermx._domainkey.yourdomainname.tld. TXT "v=DKIM1; t=s; p=public key"

 

"v=DKIM1\; t=s\; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDb6VDQw8QhpwAhZwoFCm4fIh4qx4BgrFGN+vlcBGj+vVYPij8ZuNIav2FuR8vo2YMDIZ+fAGuEXHQep/8+pVcITZdX+hsnItQXyojQ9pUl0XvHvLoSdsxBjYCOMFiZmjS/UqZbYrVOm3Cc3k2+wuoPh6U9LyYhJS9iRNg+jaZ4tQIDAQAB"
