好的 – 我放弃了试图find答案，所以在这里我:)
我有使用虚拟帐户的后缀/ dovecot设置。 我基本上遵循这个指南http://pietervogelaar.nl/ubuntu-12-04-install-postfix-dovecot-and-vimbadmin/
但是我理想的是build立一个邮件服务器作为一个域的端点，同时转发其他域。
例
example.com是邮件服务器上本地托pipe的虚拟域。 [email protected]是本地服务器上的电子邮件地址，因此邮件存储在/var/vmail/example.com/info中
otherdomain.com是一个域，它需要所有的邮件转发到some.other-server.com，而首先通过垃圾邮件/ AV检查。 没有邮件或帐户存储在本地。

〜这个邮件服务器将会中继（即发送到别处）
user = myuser password = mypassword hosts = 127.0.0.1 dbname = mydatabase query = SELECT domain FROM domains WHERE domain = '%s' and relay = 1 and enabled = 1

〜如果要将一个域转发到另一个域，请在alias_domains表中添加转发域，然后在alias_maps表中添加一个路由，例如@ alias.com @ goto.com。
user = myuser password = mypassword hosts = 127.0.0.1 dbname = mydatabase query = SELECT domain FROM alias_domains WHERE domain = '%s' AND enabled = 1

〜用户别名例如[email protected]转到[email protected]
〜Catchall：@ example.com转到[email protected]
〜Nb。 如果您使用的域不在域表中，则必须将其添加到alias_domains表中。

〜在哪里存储虚拟邮箱的邮件，前缀为virtual_mailbox_base

/等/后缀/ MySQL的/ transport_maps
〜什么传输用于发送邮件，例如虚拟或中继
〜在这里，你可以把东西，如relay：[relay.mail-server.com]在运输领域
user = myuser password = mypassword hosts = 127.0.0.1 dbname = mydatabase query = SELECT transport FROM domains WHERE domain = '%s'
我没有看到你的configuration中的任何运输地图。 它一定是像下面的东西
transport_maps = mysql:/etc/postfix/sql/relay_transport.conf relay_domains = mysql:/etc/postfix/sql/transport.conf
/etc/postfix/sql/relay_domain.conf
user = postfixadmin password = password hosts = localhost dbname = postfixadmin query = SELECT domain FROM domain WHERE domain='%s' and transport = 'relay' and active = 1
/etc/postfix/sql/transport.conf
user = postfixadmin password = password hosts = localhost dbname = postfixadmin query = SELECT transport FROM domain WHERE domain='%s' and active = 1
注意：在说明字段中，您必须指定中继服务器的IP地址
