Postfix返回“无SASLauthentication机制”，尽pipemySQL authconfiguration看起来是有效的

我正在尝试使用Postfix + Dovecot + mySQL设置一个支持多域的邮件服务器。 我正在遵循这个指南 。

我似乎有一切设置和服务器发送dovecot SSL证书（抛出一个证书exception对话框在我的客户端），但邮件不发送或接收。

/ var / log / mail_err返回这个postfix错误：

连接到私人/身份validation失败：连接被拒绝

• Postfix认为VSFTPd是… Postfix？
• 使用电子邮件客户端在电子邮件服务器之间进行传输时，请维护邮件时间戳
• 后缀日志每5分钟显示一次相同的错误
• 电子邮件未从某些邮件服务器传送到服务器：“域没有有效的邮件交换器”
• dovecot-lmtp：没有这样的文件或目录）

/var/log/mail.log正在返回更多的细节：

再次，我没有收到或能够发送邮件。 它似乎是后缀崩溃，过早退出什么。 我出来的想法，我真的不想抹去一切，并重新开始设置。 有什么想法吗？ 这是在Ubuntu 12.04上运行的VPS

我的同事build立了一些非常严格的初始防火墙规则，这只是打开需要的端口。 目前这些端口是开放的：22,10000,25,587,993,143,110,465,21,80,443,6667。我需要打开一个特定的端口吗？
