I registered a new .xyz domain name a few days ago. The domain name was never registered by others before. I set up a postfix server on a clean ip(checked its reputation). I set up SPF, DKIM, and reverse DNS. I composed a simple email(subject: hello world, content: this is a test email) destined to outlook.com. But the email from this domain goes to outlook's junk email folder. How should I do to avoid this? And how to decode the outlook email headers related to spam such as: SpamDiagnosticOutput: 1:99 SpamDiagnosticMetadata: NSPM X-Microsoft-Antispam-Message-Info: X-Microsoft-Antispam-Mailbox-Delivery:

If you register a brand new domain and set up hosting for it, check if your new IP address is blacklisted. It could well be that, since old IP addresses are 'recycled', you have obtained an IP address that was formerly owned by a spammer.
The way to go then, is either destroy your setup with the stained IP address and start over with a fresh one, or (I wouldn't recommend this if it's possible to go with the first option), apply a request for whitelisting the IP address at the various blacklisting organisations.
To have a look what Outlook thinks of your IP address, you can submit your IP here: Outlook.com
