我在Fedora 25上build立了一个带dovecot的postfix邮件服务器。它通过Squirrelmail在Web浏览器上正常工作。 但是，仍然不能通过邮件客户端程序如Outlook和Evolution连接。
进化的设置如下：
server type: IMAP+ server: mail.domain.com port: 143 username: [email protected] encryption method: No encryption sending email server: smtp.domain.com encryption method: No encryption 当然，这里的服务器名称是假的。 刷新客户端会popup一个窗口，其中包含以下详细信息：
Mail authentication request Please enter the password for mail account "[email protected]" Add this password to your keyring (ticked)
input密码并保存不断使错误返回。 任何build议来解决这个问题？

这里是一些日志，可能是有用的：
