Incoming Emails Are Delayed

[varunsridharan]

Hello,

I am currently hosting a cPanel server myself . and I recently started facing issues with incoming emails

when I send an email from a Cpanel server it gets quickly to the party to whom I sent. but if an email sent from providers like
Google /Yahoo.etc

The email shows in inbox almost 5 min later. I really can't figure out where the issue lies. !!

but I did check Greylisting which is turned off. and I have ConfigServerFirewall installed.

Hello @varunsridharan,

I recommend sending an email from one of the remote mail servers you notice the issue with and then searching for it using cPanel >> Track Delivery. You can read more about this option on the document below:

Track Delivery - Version 82 Documentation - cPanel Documentation

documentation.cpanel.net

Thank you.

Hello @varunsridharan,

Can you browse to WHM >> Exim Configuration Manager >> ACL Options and temporarily disable the option below to see if the issue persists?

Introduce a delay into the SMTP transaction for unknown hosts and messages detected as spam

Thank you.

Hello @cPanelMichael

i did as you said. but there is no improvement over the transport time what so ever. :-(

and i am not sure if its something to do with my server setup. here is how my setup is done

1. 3rd Party DNS [ Not cPanel Builtin DNS System]
2. 2 servers [ 1. For Hosting Websites & 1. For Hosting Emails] -- Email server configured with SMTP Rely Service based on the documentation i found it in here
3. only the below services are enabled in my email server
