Issue2840

I tried to send an email with jython 2.7.1 and jython 2.7.2b2 with the attached mytest_smtplib.py. The attached image is 85 KiB in size.
The OS is openSUSE Leap 15.1. The java version is 1.8.0_222.

The program fails with:

Traceback (most recent call last):
  File "mytest_smtplib.py", line 40, in <module>
    s.sendmail(sender, receiver, msg.as_string())
  File "/usr/local/jython2.7.1/Lib/smtplib.py", line 745, in sendmail
    self.rset()
  File "/usr/local/jython2.7.1/Lib/smtplib.py", line 469, in rset
    return self.docmd("rset")
  File "/usr/local/jython2.7.1/Lib/smtplib.py", line 393, in docmd
    self.putcmd(cmd, args)
  File "/usr/local/jython2.7.1/Lib/smtplib.py", line 341, in putcmd
    self.send(str)
  File "/usr/local/jython2.7.1/Lib/smtplib.py", line 331, in send
    raise SMTPServerDisconnected('Server not connected')
smtplib.SMTPServerDisconnected: Server not connected

The log of the postfix mailserver shows:

But the same program works with python.
