How to Set Up DKIM for Barracuda Email Security Service?
October 12, 2023 | < 1 min read
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.
Barracuda doesn’t support DKIM signing for outbound emails at this time. You must set up the DKIM protocol on your mail server if you wish to use it to authenticate your domains.
Please remember that: Barracuda may add a footer to your outbound messages, which may cause unintended DKIM failures for your emails if DKIM was manually configured on your mail server.
