+1, whitelisting based on SPF or DKIM seems to work well for most lists that transmit invalid "From" values (besides ADSP, it is quite frequent to get, e.g., [email protected].) One question is whether SPF is a good method for selecting the /second party signature/, for reputation checking, in case there is no valid author domain's signature, but multiple valid signatures are present. In facts, servers that run various virtual domains on the same IPs cannot use rDNS to tell on behalf of which domain the current transmission is meant to be. _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
