Okay, so I took a look at this and I can reproduce it. It's not mhfixmsg's fault. The fault is because of the ... unusual (but valid) structure of this message, and the logic inside of show_multi_internal(). At the top level, this message has a multipart/alternative, and enters show_multi_internal(). This sets alternating, but not alternate, which is correct: /* * alternate -> we are a part inside an multipart/alternative * alternating -> we are a multipart/alternative */ The two sub-parts of the top-level multipart/alternative are a text/plain and a multipart/related. The multipart/related is decended into. It contains a multipart/alternative and multiple image/jpegs. The sub-parts of THAT multipart/alternative are a text/plain and text/html. Both of the attempts to view the those parts fail (because part_ok() returns false for both of them). But THAT causes show_multi_internal() to return NOTOK. Why? Well, alternate is passed down as "true" from the top-level multipart/alternative type. The default return code for show_multi_internal() is set to NOTOK if alternate is set. And when processing the multipart/related, alternate is true (because we're under the top-level multipart/alternative) but alternating is false (because multipart/related is not an alternate part itself). That short-circuits the multipart/related processing and it bails out at that point; that bubbles up to the top-level alternative part and you get the resulting error. Are you confused? I sure was. As for a fix ... crud, I don't know. I am reluctant to mess with that alternative part processing, as it's kind of a mess (I was planning on rototilling it for the next release). --Ken _______________________________________________ Nmh-workers mailing list Nmh-workers@nongnu.org https://lists.nongnu.org/mailman/listinfo/nmh-workers
