我的服务器在CentOS 6.5上运行Postfix 2.6.6和Dovecot 2.0.9.

问题是当我使用Outlook 2013连接到服务器(它在IMAP SMTP上连接得很好)并向自己发送测试电子邮件时,我没有收到电子邮件.看着maillog我可以看到我收到了错误

postfix/virtual[2768]: 9C3D480768: to=<user@domain.net>,relay=virtual,delay=1132,delays=1132/0.02/0/0.02,dsn=4.2.0,status=deferred (delivery Failed to mailBox /var/vmail/domain.net/user: cannot open file: Is a directory)

错误消息非常清楚,我想,嗯,这可能是我之前安装的缺陷Cyrus / Postfix安装的剩余部分.我继续删除了vmail文件夹,为域创建了一个子文件夹,并将所有内容的所有权更改为vmail：vmail.我重新启动postfix和dovecot,再次出现收件箱目录. Postfix继续抱怨,就像之前做的那样.然后我尝试删除该文件夹,然后创建一个空文件,但这只是一个dovecot问题,而不是一个后缀问题,所以现在dovecot说它期待一个文件而不是一个目录.
