Actually I am not sure if this is the correct list, as its about plugin development.. (is that users or dev?)
I have a pluging for detecting attachment file types. It uses Mail::SpamAssassin::Message::Node get_header method for getting the content type header (and thus the attachment filename). However the Content-Type header is not decoded (if it has QP or base64 encodings). This seems caused by a fix for bug 6945 (https://bz.apache.org/SpamAssassin/show_bug.cgi?id=6945) where it will skip decoding all Content-* headers. Did anyone run into this before and have a solution maybe? Or should I just introduce a new util to decode it myself?
