对不起，因为我确定问题是愚蠢的，但两天后尝试不同的configuration从谷歌和Serverfault它仍然无法正常工作。 我在后缀/鸽舍新手
升级Debian之后，我configuration了（第一次）Dovecot的Postfix。 Pop3现在工作正常，但Imap不（login失败）

好的，解决了。 问题是Pop3仍然在和老程序Courier（甚至日志显示在Dovecot上面）以及Dovecot上的Imap一起工作。 Dovecot很难configuration，因为邮件bd是手工制作的，所以我最终安装了courier-imap（即删除了Dovecot-imap），并且服务器被恢复了。
