How to Set Up DKIM for Acyba / AcyMailing?
DKIM works by adding a digital signature to outgoing email messages. This signature can be verified by the receiving email server, which can then determine whether or not the message has been tampered with during transit. In order for DKIM to work, the sending email server must generate a cryptographic key pair, which consists of a private key and a public key. The private key is used to sign outgoing email messages, while the public key is published in the Domain Name System (DNS). When an email message is signed with DKIM, the signature is added as a header to the message. The receiving email server can then use the public key to verify the signature and confirm that the message has not been altered.
DKIM authentication for your domains is supported by Acyba / AcyMailing and is advised. AcyMailing suggests that you not configure AcyMailing’s DKIM signature in such instance and take it up with your server’s hosting provider if you use your own mail servers or servers outside of AcyMailing to send your emails.
You must, however, enable DKIM if you send your emails via AcyMailing’s servers. Your DKIM public key will be provided to you during the AcyMailing installation process for you to publish on your DNS in order to activate the protocol.
How to Get Your DKIM Public Key Available for Acyba / AcyMailing
- Sign in as the administrator to your DNS provider’s administration console.
