我将Plesk(Onyx)与外部DNS结合使用。我配置了邮件，一切似乎都很好，但我不确定我的邮件配置是否正确，因为有时DMARC报告会指出SPF/DKIM验证没有通过。
我的配置：
域的DNS记录-mydomain.com和mail.mydomain.com(为mydomain.com创建了两次相同的DNS条目，子域mail.myddomain.com除外，MX条目仅为mydomain.com配置)：
-
反向DNS:
123.456.1.1 -> mail.mydomain.com -
MX:mail.mydomain.com
-
SPF:
v=spf1 +a +mx -all -
_dmarc:
v=DMARC1; p=none; pct=100; rua=mailto:mailerror@mydomain.com; ruf=mailto:mailerror@mydomain.com; fo=1; adkim=s; aspf=r -
域密钥：
o=- -
默认值_域密钥：
v=DKIM1; p=SIGNATUREHERE;
PLESK/服务器相关：
- 主机名：
zeus.mydomain.com - 邮件名称：
mail.mydomain.com
测试邮件的邮件头：

如果我想用f.e."info@mydomain.com"从地址/发件人地址？我需要将邮件名更改为"mydomain.com"吗？如果我将邮件名改为"mydomain.com"，我可以安全地删除mail.mydomain.com的DNS条目吗？如果进行了新的更新/升级，有没有办法在PLESK中配置邮件名/确保PLESK不会覆盖它？

@mfuesslin，
你应该通过这个电子邮件测试程序运行你的电子邮件，它被公认为#1电子邮件身份验证和配置测试平台。你所要做的就是向mailtest@unlocktheinbox.com发送一封电子邮件，它会在几分钟内自动回复。
一旦你得到了结果，如果你需要帮助修复它指向你的任何项目，每个人都能帮助你，因为它更具体。
mydomain.com是您正在使用的from域，对吗？您应该确保SPF、DKIM，也许还有DMARC与来自的信封进行域对齐。
顺便说一句，这就是你SPF记录中的全部内容吗？您希望能够代表您发送电子邮件的服务是什么？为什么不更具体一点呢？v=spf1 +a +mx -all
