I'm having to send this through my webmail since spamcop has blacklisted
our IBM mail gateway. :-(

Originally, I thought the problem may have been explained by this post
by Peter Grandi:
http://sourceforge.net/mailarchive/message.php?msg_id=13136173

But looking at this post again reminds me of a recent fix that I hadn't
connected to the mutt problem.

A bug was recently reported that the mtime (& ctime) of a directory is
not being updated when a file is linked into the directory:
http://www.kernel.org/git/gitweb.cgi?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=988a6490a793b73ff23aa3baf87b337152178e4d

I'm not sure if mutt adds files to a directory with a link, but this may
possibly explain the problem.  This bug is fixed in 2.6.15-rc1.
