I have earlier provided the output of `cygcheck -svr` on both machines, 
but I haven't heard from you.

I'll explore this.  It's not the most pressing issue, but it was another 
symptom of the difference between the two configurations.

It appears to my untrained eye that both machines have all partitions 
mounted binmode.  I assumed this would be the correct mode if all my mail 
messages use \n as a line separator.  However, there seems to be some 
disparity between mutt and Perl about what the line separator is/should 
be, and I think that's where the problem lies.  The filter I wrote is a 
simple Perl script that takes every line of stdin and write it to stdout 
unless it's a Yahoo! advertisement.  This works on the home machine, but 
on the work machine gives me extra ^Ms.

Thank you.
