Issue Issues with Email Deliverability on Plesk Server

[myra_john]

Hi everyone,

I'm facing a frustrating issue with email deliverability on my Plesk server and could really use some help. Emails sent from my domains are either ending up in recipients' spam folders or not being delivered at all. Here are the specifics of my setup:

• Plesk Obsidian 18.0.42 on CentOS 7.9
• Mail server: Postfix
• DKIM, SPF, and DMARC records are correctly configured
• DNS settings have been verified and appear correct
• Reverse DNS (PTR) is set up

I've checked the mail logs, and I don't see any obvious errors. My IP isn't blacklisted, and I've run multiple spam tests, all of which report low spam scores. Despite all this, the problem persists.

Has anyone experienced similar issues or have any suggestions on what else I can check or configure to improve email deliverability? Any insights would be greatly appreciated!

Thanks in advance!
