问题
我非常仔细地遵循了教程,仅更改了一些小问题.
我到达了“测试邮件传递”并运行了echo test | mail test@chefdovecot.com
由于发现/ var / vmail没有显示任何内容,因此邮件未到达.
在服务器syslog中,存在以下错误：
postfix/pickup[16842]: 019023A06AB: uid=1000 from=<vagrant> postfix/cleanup[19542]: 019023A06AB: message-id= <20130620140358.019023A06AB@mail-server-berkshelf> postfix/qmgr[16843]: 019023A06AB: from=<vagrant@mail-server-berkshelf.localdomain>,size=382,nrcpt=1 (queue active) dovecot: lda: Debug: Loading modules from directory: /usr/lib/dovecot/modules dovecot: lda: Debug: Module loaded: /usr/lib/dovecot/modules/lib90_sieve_plugin.so dovecot: lda: Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Connection refused dovecot: lda: Fatal: Internal error occurred.

“连接被拒绝”错误应该是我正在攻击的错误,对吧？我在很多地方搜索过,以了解这里发生了什么,但没有发现任何有用的东西.
任何人都可以提供任何线索或见解吗？解决方案会很棒,但我很乐意接受一些新的想法来尝试.
尝试停止dovecot和postfix,删除/ var / run / dovecot / auth-userdb中的套接字文件,然后再次启动postfix和dovecot(确保用户dovecot正在运行,因为它具有/ var / run / dovecot的权限).通常这将解决此类问题.
Netstat还将显示unix域套接字.检查其输出(使用netstat -nvlap | less并搜索路径或dovecot)以确保dovecot正在侦听.
