[赵军昱]

New submission from 赵军昱 <200612453 at qq.com>:

The following bug occurs when you connect after creating an instance of SMTP_SSL:
```
import smtplib


smtp_server = "smtp.163.com"
con2 = smtplib.SMTP_SSL()
con2.connect(smtp_server, 465)
```
ValueError:
server_hostname cannot be an empty string or start with a leading dot.
  File "E:\code\noUse.py", line 8, in <module>
    con2.connect(smtp_server, 465)
