I thought so at the beginning too. But this domain is spread in many countries and every country having its own MTA. Only one of these MTAs is the offender, but all users are behind the same domain.com. Off the record, I have succeeded adding the mime lines with Postfix using: # header_checks /^Date/ PREPEND MIME-Version: 1.0^MContent-Type: text/plain^MContent-Transfer-Encoding: 8bit But again, like the 7bit conversion, it is only working if the header is already mime compliant. So it is of no use, I'll stick with formail as filter. RC.
