Version: 1.8.1 (using KDE KDE 3.4.1) Installed from: SuSE RPMs OS: Linux An attachment of type message/rfc822 is placed in a multipart/mixed wrapper with an illegal content-transfer-encoding (quoted-printable) applied to message/rfc822. That is a violation of RFC 2045 section 6.4 and RFC 2046 section 5.2.1: No encoding other than "7bit", "8bit", or "binary" is permitted for the body of a "message/rfc822" entity. Bug 1492 had covered this issue, but it is marked as CLOSED and FIXED, whereas the problem clearly still exists.
Created attachment 11864 [details] illegal message generated by kmail 1.8.1
