This mailing list removes the DKIM signature of the poster. An ADSP policy of "all" means that all mail from the domain is signed with an Author Domain Signature (d= tag). As there isn't a valid DKIM signature, the message can get rejected. If the ADSP policy is "discardable" and there isn't an Author Domain Signature, the mail can be discarded, i.e. you don't even want a rejection. If this mailing list did not remove the DKIM signature, the receivers would still get an invalid signature as the mailing list modifies the subject line and adds a footer. The ADSP policy will be interpreted as above. Regards, -sm _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
