DKIM configuration

Setting Up DKIM Key

When you send emails from our SMTP servers, they are automatically signed with a DKIM signature using keys. You don't need to configure any DNS values or generate any keys yourself.

If you require a custom DKIM key that we generate for you, follow these steps:

  1. Contact our support team to request a dedicated public key generated for your domain name.

  2. Once you receive the custom public key, add it to your DNS as a TXT record, following the format:


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


be aware that it is necessary to eliminate any whitespace from your public key string.

Once DKIM keys are defined DMARK record can be set up.
