I don't think the hotmail web interface is sophisticated enough to allow
you to do this.  Other mailers, like pine, will present each message in
the digest as an attachment to the main digest message, and you'll be able
to reply to any of them.  I know there's a script around for fetching
Yahoo! mail messages in mbox format, so you can use pine locally on your
machine.  No doubt there's a similar one for hotmail somewhere.

Any particular reason you're not using cron?

You might want to try writing the output of "cygcheck -svr" to the output
file from that script as well.

Huh?  Why do you need a batch file to catch stderr messages?  I must be
missing something.

You should be able to detect this situation by the return code from bash,
and write the output of "cygcheck -svr" only in the failing cases.
Another possibility is running this under strace, waiting for it to fail,
and, if it failed, saving the strace output and looking through that.
