That's also what I get from your posts on mailop, signature verification failed (otherwise would 've been body hash mismatch). Can you turn on z= tags? Otherwise try carefully comparing the signed fields, from: subject: to: date:, message-id: and the signature itself. Check that no other filters alter those fields after signing. Can you sign messages off-line? Do Bcc: copies verify? (Use any off-line dkim verifier.) Good luck Ale -- _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
