The phenomenon hasn't yet happened enough for me to detect a pattern, although the instance that made me start this thread was a message I sent to a googlegroups mailing list; it was fine when I sent it, but when the list sent me a copy, it was QP-encoded. > Also, for a message that _was_ QP encoded badly, can you show us the exact > headers as they are in your copy in $record?

It turns out that there was no bogus QP encoding, at least not in the sense of 'bogus' that would mean "they attemtped to QP-encode it but screwed it up in the process". I had earlier reported that the message in question was utf8 that was (unexpectedly) QP-encoded, but reported by the headers as being latin1. I was wrong about this; the headers did say utf8 after all. This whole half of my problem was due to my QP-decoding apparatus in Vim not being able to handle multibyte. > Um, one more thing.

Yes, this seems likely to me too. > Can you reliably reproduce the issue? No, not yet anyway. If I eventually can, I'll try your suggestion of forcing mutt to emit utf-7; I presume that's what $send_charset is for. --Jack
