Look in the mutt manual for Chapter 4, Advanced Usage, and Section 2, Patterns: Searching, Limiting and Tagging. > The reason I ask is I had "x-" as one of the patterns, precisely as the > documentation suggests (in an offhand example). But Mario's posts from > today have an X-URL header and it was not weeded. It is when I add > "x-url" to the ignore. What gives? Patterns are case-insensitive as long as they contain only lower-case letters. If you include an upper-case letter in a pattern, or include a range (e.g., [a-z]) that because of your locale includes an upper-case letter, the pattern becomes case-sensitive. That could be why "x-url" in the pattern is not matching "X-URL" in the header, but that's just a guess. Regards, Gary
