Based on the verification information I saw from this, it's going to be pretty difficult for Nch's emails to appear genuine if going through the mailing list; there are multiple verification steps that seem almost impossible to comply with after the list has altered the message. I wonder whether it might be a sensible idea to get the mailing list to rewrite From: addresses, thus making the entire From-address verification step moot? (Perhaps only in the case of known problematic mail providers; does our software have an option for that?) -- ais523
