""" - It needlessly used the makefile() method for each response that is read from the SMTP server. - If the remote SMTP server closes the connection unexpectedly the code raised an IndexError. It now raises an SMTPServerDisconnected exception instead. - The code now checks that all lines in a multiline response actually contains an error code. """ The Dragon approves.
