Message73504
when a SMTP object tries to send a mail through TLS, the smtp server
replies retcode 502.
When a test code (sendmail_test.py) is executed on Python 3,
it stacks on sending mail while the test code works on Python 2.5.
Following is the result of the test.
The first half is the result on Python 2.5.
A mail has been sent without any problem.
The second half is the result on Python 3.
Upto AUTH, it works fine.
But when it sends mail, the server replies retcode 502.
This is the message of failure:
send: 'mail FROM:<lambda.let@gmail.com> size=176\r\n'
reply: b'502 5.5.1 Unrecognized command. u8sm8612791tia.6\r\n'
