Email Works via IMAP But Not POP3 - cPanel
This problem is probably happening because the wrong POP3 server is running. To fix this, follow these instructions:
1) Login to your Linux box via SSH as root.
2) Run the following command:
vi /etc/xinetd.d/popa3d
3) Locate the line ‘disable = no’.
4) Change the line to read ‘disable = yes’.
5) Save and close the file by pressing ‘esc’ and typing ‘:wq’.
6) Now restart the xinetd service: ’service xinetd restart’.
7) Login to WHM and navigate to: WHM > Restart Services > Select the Link ‘POP3 Server (cppop)’.
When prompted to restart the service, select ‘Yes’.
You should now be able to access your cPanel email via POP3.

If you are still using cppop, that is indicative you are still using the old mbox format of storing mail. cPanel began phasing this out in 2005 and it is now officially deprecated with support for it to be removed in version 12. If you are still using mbox, you should consider moving to maildir using /scripts/convert2maildir. This is an interactive script executed via SSH as root. Note the conversion process may take a very long time (well over a day for some servers), but it will run in the background. Do not terminate the conversion halfway through as many people do, as that will result in some issues.
