ADSP is an extension showing the level of a domain's use of DKIM with SMTP. Since this is being introduced into existing infrastructure, requests for ADSP records are therefore optional. In addition, compliance with ADSP should not mandate more transactions than a receiving host finds merit in making. ADSP can recommend a series of SMTP related checks using SHOULD to reduce the number of domains where an ADSP records would be required to preclude spoofing with otherwise non-SMTP sub-domains. > 2.

RFC2821bis To ensure interchange, ADSP MUST indicate which protocol has adopted DKIM. -Doug _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
