This article covers the SPF and DKIM authentication processes for Active24 and how they are managed in Valimail. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.

To setup DKIM for your Active24 emails, please add the following TXT DKIM record in your DNS:

Name: a24._domainkey

Value:

v=DKIM1;t=s;k=rsa;p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDW6fYb2EdwHUMv94tFLrYlQF+XTt5N1KGmguewROebRvPHgrQTQZm3IzWwVyazo3e51hIkcCwVeH3txuS/Q/qu4elEEjFSUlQ3mCpZr0/we9Mzm3zkBIyjXT+K6JdGe7wMf0dJfENibrpN5+bWBm+LbZlc0iqcXDSmIfi8oHfrzwIDAQAB
