Found the post from cPanel support that helped me:
- Introduce a delay into the SMTP transaction for unknown hosts and messages detected as spam.
The SMTP receiver will wait a few additional seconds for a connection when it detects spam messages in order to reduce inbound spam. The system excludes the following remote hosts from the delay: Neighbor IP addresses in the same netblock, Loopback addresses, Trusted Mail Hosts, Relay Hosts, Backup MX Hosts, Skip SMTP Checks Host, Sender Verify Bypass Hosts, and Greylist Trusted Hosts.
This can be disabled from Home »Service Configuration »Exim Configuration Manager in the basic editor.
