In VM 8.0.11 this now becomes the following: R=?iso-8859-1?B?/A==?=cksto=?iso-8859-1?B?3w==?=d=?iso-8859-1?B?5A==?=mpfung Setting vm-mime-encode-headers-type to Q doesn't help much: R=?iso-8859-1?Q?=FC?=cksto=?iso-8859-1?Q?=DF?=d=?iso-8859-1?Q?=E4?=mpfung If I interpret RFC 1522 correctly, the method of VM 8.0.11 is plain wrong here, since an encoded-word must be surrounded by white space and is not allowed to start in the middle of a word (RFC 1522 section 5): | Ordinary ASCII text and encoded-words may appear together in the same | header field. However, an encoded-word that appears in a header field | defined as "*text" MUST be separated from any adjacent encoded-word or | "text" by linear-white-space. And of course the MIME decoder shouldn't look for "=?" in the middle of a word, but display the above as plain ASCII text (RFC 1522 section 6.1). ulm@gentoo.org 2008-09-15 14:36:41 0000 Package masked ~app-emacs/vm-8.0.11.581. Broken RFC conformance is serious enough to justify this. ulm@gentoo.org 2008-11-06 22:27:04 0000 Should be fixed in 8.0.12.
