Ed, there was no need to Cc: me -- I read the list.  Please make sure your
mailer respects the Reply-To: header, which I set appropriately.

That's not what I asked (though I can see how it can be misread).  Let me
try again: if you copy telnet.exe into your home directory, *leave*
/usr/bin/telnet.exe in place, and then invoke the telnet in your home
directory as /home/Ed/telnet.exe, does it still work for you?

Either the attributes, or the contents.

IIRC, the Windows dynamic loader will first look for DLLs in the
application directory, and only then in the PATH.  Here's a WAG: do you
have a copy of winsock.dll or ws2_32.dll in /usr/bin?

Just to rule out traverse checking, could you try running
"CYGWIN=notraverse /usr/bin/telnet HOST"?

Doesn't look particularly significant...  Can you also post the output of
"getfacl / /bin /home/Ed"?
