It almost sounds like someone's tried that using X on a cellphone. ;-)

Why yes, /usr/bin/folders is owned by the libmtp0 package.

/usr/local/bin/folders is owned by my nmh package.  /usr/local/bin
is ahead of /usr/bin in my PATH.

I did run "Find all folders" in exmh before sending my initial email. 
That didn't fix the folder list in exmh.

But, because of your hypothesis about two 'folders' existing, I 
experimented with removing execute permission from /usr/bin/folders,
restarting exmh, and running "Find all folders". The result is the
correct folder list in exmh.

I'd rather not mess with /usr/bin/folders permissions, and am hoping 
that there's an exmh or nmh way to lock 'folders' to /usr/local/bin/folders.
If not, then I can write a shell script that forces my path      
before calling exmh.  After all, what else besides a conditional 
path order could have caused this?                               

Thanks!!!
