Hello, community

We run webspace and mailboxes for customers, currently Plesk is in use. It’s quite inflexible and we didn’t see any evolution in the product, so the eye went on cPanel.

We run Webspace and mailboxes separately and I would like to understand, what cPanel can do as the Mailserver. Here is what we want:

1) All Mailboxes of the customers on one machine (We manage the DNS, too)

2) A very simple Customer’s-Interface, preferably customizable, to manage their Accounts

3) A Webmail-Interface for the customers, maybe RoundCube

4) Obviously ssl-Access to these Webinterfaces, even if the real webspace runs somewhere else. Somehow it needs to be able to request certs only for webmail.domain.xxx

5) Preferably dedicated WebMail-URLs: webmail.customer1.com, webmail.customer2.de, etc.

6) Encrypted E-Mailing, DKIM

7) Preferably dedicated Mail-URLs: mail.customer1.com, mail.customer2.de, etc. für IMAP and SMTP

8) Autoconfig for the client-mail-programs!

Any answer appreciated! Thanks a lot for helping.

cPanel takes care of all that actually. You'll need to do some feature list editing for item 2, and I am not sure how many programs are are supported for 8, but cPanel's mail system is pretty robust.

Hello @OlafKapinski,

You can technically use a full cPanel license on a server and create full cPanel accounts with the intention of only using the server's email capabilities. However, keep in mind there's no integration with the control panel you're using to host the domain's website and/or it's other services. Thus, your users would have to manage all aspects of their email accounts (e.g. email account creation, webmail) on the cPanel server that's setup for email hosting.

It's still early in the implementation process, but you can review the current road map for the functionality you may find more helpful:

Server Profiles Roadmap - cPanel Knowledge Base - cPanel Documentation

Additionally, you can follow the feature request below to receive updates to this feature as they are delivered:

Mail Only version of cPanel & WHM

Thanks!

I would like to have more details on the following point if someone can forward me the configuration of Encrypted E-Mailing:
Hello @Jean Boudreau,

DKIM verifies the sender and the integrity of a message. In addition, it allows an email system to prove that spammers did not alter an incoming message while in transit. DKIM also verifies that the messages your server receives come from the specified domain.

The individual emails are not encrypted on the server, if that's what you're interested in knowing. Email encryption is generally enabled on an email-user's workstation with the use of technologies such as S/MIME or PGP to sign, and encrypt, individual messages. This is not implemented directly in cPanel, as it involves the sender and receiver configuring these features in their specific email clients. That said, I encourage you to vote and add feedback to the following feature request if you'd like to see this type of feature integrated directly with cPanel & WHM:

Encrypt email with s/mime certificate

Thank you.
