我希望MTA发送来自两个域的电子邮件，由同一台服务器发出。 电子邮件从一个域发送，但从另一个失败。
我的应用程序服务器生成smtp电子邮件作为mydomain.com或mydomainother.com
应用程序服务器继续
ipv4: 1.1.1.1 ipv6: 1111:1111:...0001 并作为mydomainother.com提供页面
无论哪种方式发送到服务器2上的相同的MTA
mta住在
ipv4: 1.1.1.2 ipv6: 1111:1111:...0002
手册网站mydomain.com住在ipv4：1.1.1.3
mydomain.com的邮件服务器是Outlook（不要模拟，我没有select）
MTA是postfix，带有opendkim插件。 它收到并中继邮件正确的mydomainother.com它从中继邮件mydomain.com与谷歌SPF失败弹回它们时失败
mydomainother.com有这些DNS条目：
inventryanywhere.co.uk. 14400 IN TXT v=spf1 mx a ip4:1.1.1.1/32 ip4:1.1.1.2 ip6:1111:1111:...0002/128 ?all dkim._domainkey.mydomainother.com. 600 IN TXT v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCt79QysuOC7QU2h0w7eKSZyptVkZkPD/zqTqmzq3ZNpqz5YmunBatGhESYea5RX51CpQHbcH0gmAN0tXvz7jCIi+2xyDyVe+Ay/EW4D72DNU+a0Ckr6lPdsS0lpNg7A8/RzDO4+m2n1E7ZrImFp+3MZz6q5pQPm5DzqOoDCTTRnQIDAQAB; s=email
（记住，这些出去很棒 – heres syslog：）

另一个域在SPF上失败，这里是我为域设置的DNS：
mydomain.com. 14400 IN TXT v=spf1 ip4:181.224.128.60 mx a ip4:1.1.1.1/32 ip4:1.1.1.2 ip6:1111:1111:...0002/128 include:outlook.com ~all mail._domainkey.mydomain.com. 600 IN TXT v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCt79QysuOC7QU2h0w7eKSZyptVkZkPD/zqTqmzq3ZNpqz5YmunBatGhESYea5RX51CpQHbcH0gmAN0tXvz7jCIi+2xyDyVe+Ay/EW4D72DNU+a0Ckr6lPdsS0lpNg7A8/RzDO4+m2n1E7ZrImFp+3MZz6q5pQPm5DzqOoDCTTRnQIDAQAB; s=email
所以基本上，两个域的SPF和DNS条目是重复的，因为电子邮件将从相同的MTA和应用服务器发出。 那么为什么从mydomain.com发送呢？
