The IMAP server %S does not seem to support encrypted passwords. If you just set up the account, please try changing to 'Password, transmitted insecurely' as the 'Authentication method' in the 'Account Settings | Server settings'. If it used to work and now suddenly fails, this is a common scenario how someone could steal your password.
这台 IMAP 服务器 %S 似乎不支持加密过的密码。如果您刚设置好您的账户，请尝试把“账户设置 | 服务器设置”中的“验证方式”修改至“不安全传输的密码”。如果之前一直正常，但是现在突然出错，很可能有人正在盗取您的密码。
