我试图让后缀通过我的smtp帐户与另一个电子邮件提供商发送电子邮件（在这种情况下lavabit.com）
我收到错误
收件人不被识别。 中继访问被拒绝
这使我想它试图发送电子邮件到外部smtp和拒绝它，因为没有该地址的帐户，而不是与我的帐户login身份validation，并通过外部smtp作为该帐户（我）发送电子邮件。
我的sasl_passwd文件显示如下：
mail.lavabit.com [email protected]:password 和我的master.cf读取：
# See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name.

同时， relayhost_maps是空的，尽pipe最终我想使用它，只转发一个地址的电子邮件不是全部。
好吧，其实是不authentication的原因是我需要：
smtp_sasl_auth_enable = yes
不只是：
smtpd_sasl_auth_enable = yes
因为smtp_sasl_auth_enable是postfix（后缀发送电子邮件）的smtp客户端部分，
而smtp_sasl_auth_enable是postfix（后缀接收电子邮件）的smpt服务器部分，
