Hello,

I have a cPanel&WHM version 74.0.8.

I´m trying to connect to my e-mail account with POP3 protocol over port 110. I can´t.

Is default behavior of cPanel to use secure ports POP3 995?

Also, is default behaviour of cPanel that use SMTP port 465? I can´t use port 25.

Best regards,
Elizabeta

Hello @Elizabeta,

Ports 110 and 995 are setup by default for POP3 on cPanel & WHM. Ports 25 and 465 are setup by default for SMTP. Make sure the ports on the following document are open in your system's firewall rules:

How to Configure Your Firewall for cPanel Services - cPanel Knowledge Base - cPanel Documentation

If they are, then it's possible your ISP is blocking those ports. You may want to reach out to your ISP support team to verify if that's the case.

On WHM-Home-Service Configuration-Mailserver Configuration-Allow Plaintext Authentication (from remote clients) is it recomended option Yes or No ?
The default value is "Yes". When this option is set to “No”, only connections originating on the local server will be allowed to authenticate without encryption and thus attempts to authenticate over the non-SSL ports would fail.

Thank you.

Hello Michael,

Thank you very much for your answer.
If I put on WHM-Home-Service Configuration-Mailserver Configuration-Allow Plaintext Authentication (from remote clients) is it recomended option Yes, I have not problem with checking mail POP3 for 110 and 995 ports. It´s works.

I have asked, what is recomended value for cPanel&WHM (ok default is Allow Plaintext Authentication (from remote clients) Yes),
but what you sugested us?
To allow POP3 ports both 110 and 995, or just 995?

Best regards,
Elizabeta

Hello @Elizabeta,

It depends on your preferences and the needs of your customers. Forcing encrypted authentication for POP3/IMAP allows for a more secure environment where the likelihood of compromised login credentials is decreased. However, it may also lead to more login failures and support requests from customers using unencrypted connections.

Thank you.
