Just for the record, Hans got some help on his question about sending SMTP 
mail
and starttls.

Dear Rob,

Thank you for following up about this.  I got a reply, but from the
ding.gnus list, rather than from the help-emacs-windows list.  I will
paste the reply in below, as well as my followup.  In short, the
problem is solved!  The problem boils down to the fact that the
command

(signal-process (process-id process) 'SIGALRM)

does not work with Win32 Emacs, even with Cygwin also installed.  But
one can mimic that with:

(call-process "c:\\cygwin\\bin\\kill.exe" nil nil nil
                                     "-ALRM" (format "%d" (process-id 
process)))

or in some other way, e.g. by using 'shell-command'. 

It seems to me that this is worth getting into the help-emacs-windows
archive.  Do you want to reply to my original message with this
information?

Thanks,
Hans
