Postfix无法找到/ etc/postfix /虚拟文件

Question

在Ubuntu Server 12.04计算机上,我为特定地址设置了一个电子邮件转发器/etc/postfix/virtual:example@mydomain.com postfix-test@dotancohen.com

地址postfix-test@dotancohen.com工作和接收邮件.当我发送邮件给example@mydomain.com我时,在日志中得到这个:

warning: hash:/etc/postfix/virtual is unavailable. open database /etc/postfix/virtual.db: No such file or directory
warning: hash:/etc/postfix/virtual lookup error for "example@mydomain.com"
warning: 705B58190E: virtual_alias_maps map lookup problem for example@mydomain.com  -- deferring delivery

为什么postfix无法找到/etc/postfix/virtual file？

$ cat virtual
example@mydomain.com post-test@dotancohen.com

$ cat main.cf | grep virtual
virtual_mailbox_domains = mydomain.com
virtual_mailbox_base = /var/mail/vhosts
virtual_mailbox_maps = hash:/etc/postfix/vmailbox
virtual_minimum_uid = 100
virtual_uid_maps = static:5000
virtual_gid_maps = static:5000
virtual_alias_domains = fastupfront.com
virtual_alias_maps = hash:/etc/postfix/virtual
# virtual_alias_maps = /etc/postfix/virtual # I tried without the 'hash:' prefix as well.

请注意,这mydomain.com是匿名的.实际上,文件中使用的域名是一个真实的域名,它的A和MX记录指向该服务器的IP地址,并为Apache提供服务的网页.DNS记录上周发生了变化,所以我知道它们已经传播了.

问题是编辑后需要执行以下命令/etc/postfix/virtual:

$ sudo postmap /etc/postfix/virtual
$ sudo service postfix reload
