我有一个预装了 DirectAdmin 和 exim 邮件服务的 VPS。但我收到了客户的投诉。
当他尝试从他的帐户向某人发送电子邮件时，该电子邮件被标记为垃圾邮件。
这是包含所有标题和内容的完整电子邮件。我希望有人能帮助我

答案1
让我们看一下您的外部邮件设置。
首先，你的 MX 记录有点奇怪（这与垃圾邮件文件夹无关，但你应该修复它。每个 IP 只包含 1 条记录，
[~] host -tmx dutchtwinz.com
dutchtwinz.com mail is handled by 10 pop.dutchtwinz.com.
dutchtwinz.com mail is handled by 10 smtp.dutchtwinz.com.
dutchtwinz.com mail is handled by 10 mail.dutchtwinz.com.
dutchtwinz.com mail is handled by 10 imap.dutchtwinz.com.
dutchtwinz.com mail is handled by 10 pop3.dutchtwinz.com.
它们都指向您的单个 IP 141.138.205.229，因此只需删除所有保存的邮件，它看起来就会更正常。
你的 IP 有一个 PTR，并且它会解析回你的 IP，所以这很好。
[~] host 141.138.205.229
229.205.138.141.in-addr.arpa domain name pointer 117.lemoninternetbureau.nl.
[~] host 117.lemoninternetbureau.nl
117.lemoninternetbureau.nl has address 141.138.205.229
117.lemoninternetbureau.nl has IPv6 address 2a02:348:84:cde5::1
并且您的邮件服务器的名称为 HELO
[~] telnet 117.lemoninternetbureau.nl 25
Trying 141.138.205.229...
Won't send login name and/or authentication information.
Connected to 117.lemoninternetbureau.nl.
Escape character is '^]'.
220 117.lemoninternetbureau.nl ESMTP Exim 4.82 Sun, 21 Sep 2014 16:11:21 +0200
所以这很好。A == PTR == HELO。
[~] host -t spf dutchtwinz.com
dutchtwinz.com has no SPF record
[~] host -t txt dutchtwinz.com
dutchtwinz.com descriptive text "google-site-verification=TA_T5RfvDX1R2fsaq29sQsAg1e0LFtFi8OWduzmZNrw"
dutchtwinz.com descriptive text "v=spf1 a mx ip4:141.138.205.229 ip6:2a02:348:84:cde5::1 ~all"
您的域名有涵盖您主机的 SPF 记录。我没有在标头中看到 DKIM 签名。您可以尝试启用 DKIM，因为这有助于向 hotmail 发送邮件。
此外，从外观来看，您似乎没有发送很多电子邮件，并且您的 IP/域名的声誉也不太好。所以这可能对您也不利。
您应该告诉您的客户在 hotmail 中将邮件标记为非垃圾邮件，这有助于将来的邮件不会进入垃圾邮件文件夹。
