cPanel Technical Support has been heavily impacted by hurricane Beryl and our ability to respond to tickets has been hindered as a result. We appreciate your understanding and patience as we address these delays.

Deferred due to greylisting question

    Hello :), Firstly, check if the server IP is blacklisted with any Database or not. Email Blacklist Check - See if your server is blacklisted Also setup SPF and DKIM for your domain so that the email you send can get authenticated by the recipient mail server.

    Incoming mail is can be deferred by Greylisting if you have enabled the Greylisting service. If the Greylisting filter is enabled, the message you are seeing is quite normal, and will be applied to all incoming mail that your server receives. Please see Greylisting - Version 64 Documentation - cPanel Documentation for full details. WHM Server wide settings Home >> Email >> Greylisting Individual cPanel Account settings (per domain) cPanel >> EMAIL >> Configure Greylisting

    Hello, It's normal to see message deferrals when Greylisting is enabled: Greylisting - Documentation - cPanel Documentation To clarify, are new incoming messages still deferred after disabling this feature? Thank you.
