Since just the Internet domain owner/administrator may add custom DNS records, the TXT record works as a verification of ownership for the corporation providing the service. Another popular use for this sort of records is the e-mail SPF (Sender Policy Framework) security, which ensures that an email address shall not be spoofed and that others will not get spam from allegedly your mailbox. The TXT record includes details about the mail server where your online messages originate from and serves as proof that it is a trusted one. As there are no rules concerning the content of this sort of a record, you can include any other info also.
