The double quotes around the "human readable" part of the email address are not allowed. Python is handling this correctly.

Note, however, that python3 will compensate for this bug in the input, and register a defect for it: >>> import email >>> import email.policy >>> msg = email.message_from_string('To: "=?gb18030?B?bWFpbGZvcnRlc3R0?=" <2070776562@qq.com>\n\ntest body', policy=email.policy.default) >>> print(msg) To: "=?gb18030?B?bWFpbGZvcnRlc3R0?=" <2070776562@qq.com> test body >>> msg['To'] 'mailfortestt <2070776562@qq.com>' >>> msg['To'].defects (InvalidHeaderDefect('encoded word inside quoted string',),)
