Another popular use for this type of records is the e mail SPF (Sender Policy Framework) protection, that helps to ensure that a particular email address won't be spoofed and that others will not get junk mail from allegedly your mailbox.

Since there are no standards concerning the content of this type of a record, you can include any other info also.
