That's correct. The general guidance is it's a good idea to avoid : in MacOS filenames, because of this, but there's no hard prohibition nor, I think, a security issue. Generally speaking GUI apps that use the system GUI routines will exchange a : in a filename for a /, and vice-versa. For instance, if I create a file called "a:a" bash$ touch a:a then the Finder (MacOS's file browser, equivalent to the Windows Explorer, etc.) displays the file as "a/a". This presents a lot of confusion and is good reason for users to avoid either character in the contexts in which it is permitted, but not, I think, an issue mutt needs to worry about overmuch. > Cameron (or anyone else on MacOS), can you confirm ':' is allowed for files > on your system, especially those created from a shell or launched by Mutt > via mailcap? Confirmed. And this is not a recent change. It has been ever thus since MacOS X, the Unix-based MacOS was introduced. -- jh...@alum.mit.edu John Hawkinson
