This article explains how to set up email services on a Cloud Server with Plesk.
For any Cloud Server using Plesk, applications such as email should always be installed and managed using the Plesk interface.
For security reasons, SMTP port 25 (outgoing) is blocked. If you want to unlock the SMTP port, please contact customer service.
You have set up a Cloud Server with Plesk (any operating system).
You have enabled the ports required for using POP3 or IMAP in the Cloud Panel in the Network > Firewall area.
POP3: Port 110 TCP and/or Port 995 TCP
IMAP: Port 143 TCP and/or Port 993 TCP
In order to receive email with your domain, you need to make sure that the DNS is set up correctly.
Log in to IONOS.
Edit the DNS settings for your domain. To do this, you need to specify the provider's mail servers in the MX records of the domain. With these, you determine which mail servers are responsible for receiving emails for this domain.
You can easily edit existing MX records for the desired domain/subdomain by clicking on Edit Record under Actions.
If you have not yet added an MX record, click on Add Record and then on MX.
In the Host Name field, specify the host you want, such as @ or a subdomain. The @ character is used as a wildcard in this case and ensures that the domain is called with www and all subdomains.
In the field Points to, enter the desired entry, such as mx1.mymailserver.com.
In the Priority field, enter 10.
If you are using multiple mail servers, you can use the priority to determine which mail server is preferred. The mail server with the lower priority number is given priority. After that, the mail server with the next highest priority is selected - if the priority is the same, the decision is made randomly.
Optional: Select the desired TTL (Time-To-Live).
By default, your settings are active immediately.
Your changes are effective immediately at IONOS. However, it can take up to 1 hour for the change to take effect everywhere due to the decentralized structure of the Domain Name System.
Alternatively, you can generate a secure password.
In the Mailbox area, select the desired mailbox size.
By default, the Default size (Unlimited) option is enabled. We recommend that you set a limit for each mailbox.
To create the account, click OK.
