Brilliant! :-) That was it. I've not seen an error like that before but I guess it must be because of when I did something to that message relative to when the mairix index was built.
You replied to that message. That's what the R in the filename means. See Wikipedia on maildir: <https://en.wikipedia.org/wiki/Maildir>
Apparently you use mairix on a live set of messages. If so, this will be an ongoing problem. You might want to rebuild mairix's index automatically, perhaps nightly.
