Doesn't seem like it works.  I get the following output.  `C-d' was
typed after the line with "220 OpenSSL...".  After I inserted "EHLO
foo <RET>" about 20 seconds passed and then the indicated error was

c:\foo>gnutls-cli --port 25 --starttls smtp.web.de
gnutls-cli --port 25 --starttls smtp.web.de
