Hi all, First of all, these messages aren't scam as come from legitimate professionals I know (doctors, lawyers, etc...), who probably also struggle a bit with the latest "feature changes" of Thunderbird. The point is this: - I receive the mail but the mail has a "send" button (maybe the receipt?). - If I click "send", the original mail VANISHES and I get a draft mail which has the addreses that the original senders used as "To", but no sign of the e-mail address of the sender!!! - The mail is flagged as "This is a draft message". How I stop this''' insanity''' for good? Thanks and Kind Regards, Skarm
