The reason why the CEO did not receive an important message expected from a trusted sender after adding them to a safelist is because end-user safelists apply to antispam engines only. End-user safelists are lists of sender addresses or domains that end users can create and manage through their quarantine accounts or email clients. End-user safelists allow end users to accept or exempt messages from certain senders or domains from being identified as spam by the antispam engines.

A TXT record is a type of DNS record that contains arbitrary text data that can be used for various purposes such as verification, configuration, or authentication. A TXT record can contain the DKIM public key per RFC 6376, which is used to verify the digital signature of an email message generated by the DKIM private key of the sender domain.

The other options are not valid because:

A) A CNAME record is a type of DNS record that maps an alias name to a canonical name or another alias name. It does not contain any DKIM public key information.

B) An AAAA record is a type of DNS record that maps a hostname to an IPv6 address. It does not contain any DKIM public key information.

D) A PTR record is a type of DNS record that maps an IP address to a hostname, which is the reverse of an A or AAAA record. It does not contain any DKIM public key information.
