如果本地交付在postfix中失败，我如何将外发邮件发布到互联网？
我的服务器有configuration了mydomain.tld的虚拟域。 当我发送电子邮件到[email protected]它尝试本地交付，如果没有find用户失败。 相反，我需要将这些邮件发布到互联网上。
上述要求的原因是我有多个服务器configurationmydomain.tld。 不同的用户在不同的服务器，但同一个域 – mydomain.tld（我有一个传入邮件的工作机制）
这是我的main.cf文件。

我build议你删除所有的virtual_mailbox_ *参数，只使用transport_maps和relay_domains。
在master.cf中设置“dovecot：”运输，通过dovecot LDA或dovecot LMTP发送邮件。 例如：
dovecot unix - nn - - pipe flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/dovecot-lda -f ${sender} -d ${recipient}
接下来的动作是把mydomain.tld附加到你的relay_domains。
之后，为transport_mapsconfiguration一个SQLconfiguration文件，为每个现有用户提供诸如“dovecot：”的结果。 否则不要在这里返回任何东西。 还可以使用以下条目为transport_maps创build散列表：
mydomain.tld [other.mailserver.mydomain.tld]
最后一行是mydomain.tld的默认中继主机。 任何匹配的电子邮件地址将覆盖此默认值，因此会传送到您的本地dovecot服务器。
