I downloaded Python 2.2.2, compiled and installed. Now
starttls() generate problem:

> send: 'STARTTLS\r\n'
> reply: '220 OpenSSL/0.9.5beta go ahead\r\n'
> reply: retcode (220); Msg: OpenSSL/0.9.5beta go ahead
> Traceback (most recent call last):
>   File "aa", line 12, in ?
>     server.starttls()
>   File "/usr/local/lib/python2.2/smtplib.py", line 591, in starttls
>     sslobj = socket.ssl(self.sock, keyfile, certfile)
> AttributeError: 'module' object has no attribute 'ssl'

Any help?
