我最近在我的 debian squeeze 系统上安装了 postfix + dovecot + dkim 多域、多用户、多别名邮件服务器。除了一个大问题外，其他一切都正常，这个问题基本上让整个系统变得毫无用处：
我的服务器发送的每封电子邮件都会直接进入垃圾邮件。（gmail，hotmail）
我做的第一件事是进行众所周知的 allaboutspam 测试，除 BATV 内容（黄色）外，所有内容均已检查（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，我不知道该如何解决这个问题。如果您需要任何详细信息，请向我询问。

ciao bello ti invio il codice la prossima volta fammi sapere
答案1
您是否正确设置了反向 DNS？确保您的邮件服务器的正向和反向记录匹配。
答案2
因此，Gmail 会告诉您：
这封邮件为什么被归类为垃圾邮件？它与我们的垃圾邮件过滤器检测到的邮件类似。
这通常是垃圾内容的问题。
事实上，如果我收到一条包含“ciao bello ti invio il codice la prossima volta fammi sapere”的消息，我可能也会将其标记为垃圾邮件。它看起来确实像垃圾邮件。
你可以做两件事：
- 重写您的内容以使其更具专业的在自然界。
- 多次点击“非垃圾邮件”。
