我最近在我的debian squeeze系统上安装了postfix + dovecot + dkim多域，多用户，多别名的邮件服务器。 除了基本上使整个事情变得无用的一个大问题之外，
我的服务器发送的每封电子邮件都直接进入垃圾邮件。 （Gmail，Hotmail）
我做的第一件事是做着名的allaboutspamtesting，除了BATV的东西（黄色）之外，所有的都被检查（绿色）：
Reverse dns: green HELO Greeting: green RBL: green BATV: yellow SPF: green DKIM: green URIBL: green SPAMAssassin: green Greylist: green 我真的很困惑，我看不出解决这个问题的办法。 如果你需要的话可以问我一些细节。

你有没有正确设置反向DNS？ 确保邮件服务器的正向和反向logging匹配。
所以，Gmail告诉你：
为什么这封邮件是垃圾邮件？ 这与我们的垃圾邮件filter检测到的邮件相似。
这通常是垃圾邮件内容的问题。
事实上，如果我收到一封包含“ciao bello ti invio il codice la prossima volta fammi sapere”的邮件，我可能也将其标记为垃圾邮件。 这当然是垃圾邮件看起来不够。
