Hello, (not strictly postfix specific question, but hopefully allowed)
I have postfix for my personal use, with my own domain, hosted as VPS. (not this email account that I am sending from) Recently, several emails I sent ended up in spam on the receiving side, in all cases the mail was handled by outlook.com I have a suspicion that outlook.com somehow scores my emails as spam. (but I don't have access to the receiving party logs) I have contacted outlook support and they said my domain or ip is not on any blacklist. They also gave me link to Junk Email Reporting Program (JMRP) where I can check report for my ip address. https://paste.pics/f87244bf8a6e0e3a1a0f37a73fef80d7 I am confused what that report means, especially the part at the bottom: IPs Sending Feedback These IPs are already sending complaints as part of this feed. Metanet is my VPS hosting provider, and my IP is on the 185.46.57.0/24 subnet. And 10+ years ago, my domain was hosted at another VPS on the second 81.173.80.0 range that is also listed there. Is anybody familiar with the report and can interpret it? Also, what other tools are there to check email deliverability score? I found https://www.mail-tester.com/ and my test email scores 7/10 there. But I have no experience with these tools, and don't know how seriously I should take them . any advice would be greatly appreciated. thanks,
