使用get_mails(sender='')出现以下错误

[gitscamI]

import zmail server =zmail.server("fengfeng@qq.com","sdfsdfrozbdkberi") mail = server.get_mails(sender='PostMaster') Traceback (most recent call last): File "/work/python3/lib/python3.6/site-packages/zmail/parser.py", line 152, in parse_headers bname, bvalue = line.split(b':', 1) ValueError: not enough values to unpack (expected 2, got 1)

During handling of the above exception, another exception occurred:

上面错误的主要对象是：只要是 qq的退信，就不能正确解析。 正常收到的信不会出错，我用 server.get_mail(index)测试发现以上情况

看样子是QQ的退信不符合邮件协议规范 所以出现解析错误 这个退信通过什么可以复现么？
