I asked for ALL the headers, not just the two you show, but in any case, what I think is happening is there is more than one DKIM signature in the mail. The first is before list transformations such as prefixing the Subject: or adding a footer and the second is after. The first fails because of the list transformations and the second passes. > I set REMOVE_DKIM_HEADERS = Yes This may make a difference, but it shouldn't. According to <https://www.rfc-editor.org/rfc/rfc6376.html#section-6.1> a message with a good signature should verify even if there are also bad signatures present. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
