Extra comments regarding Mailfence Release Notes May 2024

Security Advisory: In response to a specific security issue enabling email spoofing highlighted on this page, Mailfence always DKIM signs the “Content-Type” header of all outgoing emails. To ensure our users are not affected by an additional (unsigned) Content-Type header being injected into an already DKIM-signed email (for email programs/MUAs that do not handle this case well), we have stopped using the “l=” tag. This change ensures the DKIM signature verifier verifies all parts of the email. If you are using a custom domain, we strongly recommend changing (creating a new DKIM keypair and validating it) your domain DKIM key to avoid potential exploitation of DKIM signatures made in the past.


  • Backend release 4.9.008d,
