电子邮件由procmail转发，被Gmail拒绝

编辑

让我们忽略一下我写下的所有内容，然后重新提出问题：如果您有自己的域名，并且想要将该域名的电子邮件发送到Gmail收件箱（而不是Google Apps），那么您将如何执行此操作？最好只使用SMTP，而不使用POP3。

原文问题：

我有几个虚荣的域名，其中之一是amedee.be 。
我使用Postfix在Amazon AWS主机上运行Debian服务器。
我也安装了SpamAssassin，我已经确认它会照顾最明显的垃圾邮件。
我正在使用Procmail将邮件转发到Gmail。
我使用的是Google所描述的最佳做法： https ： //support.google.com/a/answer/175365？hl = zh_CN

大多数电子邮件到达都很好，这与ServerFaultbuild议的“类似问题”不同，它只是全部或全部。但更多的时候比我想（约20），我得到这在/var/log/mail.log ：

 Nov 30 15:01:39 ip-172-31-51-67 postfix/smtp[29724]: 4B72563149: to=<amedee.vangasse@gmail.com>, relay=gmail-smtp-in.l.google.com[74.125.22.26]:25, delay=2657, delays=2657/0.2/0.07/0.18, dsn=5.7.1, status=bounced (host gmail-smtp-in.l.google.com[74.125.22.26] said: 550-5.7.1 [52.0.177.1037] Our system has detected that this message is 550-5.7.1 likely unsolicited mail.

Please visit 550 5.7.1 https://support.google.com/mail/answer/188131 for more information. y66si45484104qhc.73 - gsmtp (in reply to end of DATA command))

我已经证实，这绝对不是垃圾邮件。当相同的邮件直接发送到Gmail，它到达。

我不知道这是不是巧合，但是当我将服务器从Hetzner移到AWS时，我开始注意到这一点。我一直在使用这个设置几年，只是在过去的两个月，电子邮件迷路了。奇怪的是，我的新老服务器上的Postfix和Procmailconfiguration是相同的。

其他相关的问题提到了DKIM和SPF，我将要去调查这些字母的意思，但是过去我没有用过它，它起作用，所以首先我想排除其他明显的原因。

我的问题：我需要做什么才能使Gmail不会再popup我转发的合法电子邮件？

编辑：有人标记我的问题作为这个问题的重复：如何发送电子邮件，并避免他们被列为垃圾邮件？ 但是，我的问题不是关于发送电子邮件作为原始发件人，我的问题是关于转发别人发送的电子邮件。在我发布我的问题2分钟之后，还没有完成标记，所以我认为这是一个对angular线阅读的情况。不要感到不好，我们都希望得到StackExchange的声望。

我将继续编辑这个问题，因为我从疑似重复的地方处理每个点，直到我毫无疑问地certificate它不是重复的。

编辑：DNSconfiguration：

 * 300 IN A 52.0.177.103 @ 300 IN A 52.0.177.103 styx 300 IN A 52.0.177.103 @ 300 IN MX 1 styx.amedee.be. @ 300 IN SPF "v=spf1 ip4:52.0.177.103 ptr ?all" @ 300 IN TXT "v=spf1 ip4:52.0.177.103 ptr ?all"

编辑：根据mxtoolbox.com，我的反向DNS不匹配我的SMTP横幅。所以我在/etc/postfix/main.cf更改了我的SMTP横幅：

 #smtpd_banner = $myhostname ESMTP $mail_name. All Your Spam Are Belong To Us! smtpd_banner = ec2-52-0-177-103.compute-1.amazonaws.com

并确认Postfix重新加载后的变化：

 admin@ip-172-31-51-67:~$ telnet 127.0.0.1 25 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. 220 ec2-52-0-177-103.compute-1.amazonaws.com quit 221 2.0.0 Bye Connection closed by foreign host.

所以，据我所知， 52.0.177.103的反向域名是ec2-52-0-177-103.compute-1.amazonaws.com ，以及ec2-52-0-177-103.compute-1.amazonaws.com的IP地址ec2-52-0-177-103.compute-1.amazonaws.com 52.0.177.103是52.0.177.103 。相当不幸的是，我更希望主机名styx.amedee.be和反向DNS是相同的，但我认为这是我无法控制的。

单独使用SMTP是不可能的。您必须在个人邮件服务器（例如Dovecot）上configurationPOP3服务，然后将Gmailconfiguration为使用POP3获取邮件。用任何其他方法，你将失去电子邮件的风险。
