MailUp

DKIM uses cryptographic signatures and public-key infrastructure to verify that an email message has not been altered during transit, and that it truly came from the claimed sender. Email senders can use DKIM to sign their messages by adding a DKIM-Signature header field to the messages. Email receivers can then use the public key published in the DNS to verify the signature and check that the message has not been tampered with. 

Steps to Configure DKIM for MailUp

  • Make the following modifications to your DNS records by visiting your DNS.
  • Set up two CNAMEs (below example.com is used as an example, replace your domain name with it)
  1. ml01._domainkey.example.com 
  2. ml02._domainkey.example.com
  • Moreover, direct them (1) and (2) respectively  to the following
  1. ml01._dkim.musvc.com
  2. ml02._dkim.musvc.com
  • For more information if the CNAME cannot be generated, please contact MailUp support.
  • Remember, changes don’t start working for 24-48 hours.
