网易系163、126等邮箱imaplib.search邮件参数该如何设置？

[wenxioy]

网易系邮箱使用imap协议登录获取邮件时首先要求附带联系信息，这一步已经解决了，然后使用mail.search(None, 'ALL')也能获取到全部邮件列表信息，但是使用mail.search(None, 'TO', '"[email protected]"') 、mail.search(None, 'FROM', '"[email protected]"') 、mail.search(None, 'subject', '"cursorxxx"')等命令均返回空列表，或者一些网上看到的实例写法均未成功，不知道有没有啥解决方案。
mail = imaplib.IMAP4_SSL(self.imap['imap_server'], self.imap['imap_port'])
mail.login(self.imap['imap_user'], self.imap['imap_pass'])
imap_id = ("name", "xxx", "contact", "[email protected]", "version", "1.0.0", "vendor", "imaplib")
mail.xatom('ID', '("' + '" "'.join(imap_id) + '")')
mail.select(self.imap['imap_dir'])
addr_from='[email protected]'
search_cmd=f'(FROM "{addr_from}")'
status, messages = mail.search(None,search_cmd)

使用ALL命令搜索解读的邮件属性：

date = datetime.now().strftime("%d-%b-%Y")
status, messages = mail.search(None, f'ON {date} UNSEEN')
使用日期搜索减少返回数
