A mailbox allows you to send and receive emails using the domain hosted on your server. This guide explains step-by-step how to create a mailbox in the Plesk hosting control panel.

Step 1: Log in to Plesk

• Go to the Plesk panel using the address provided by your hosting provider (for example, https://yourdomain.com:8443).

• Enter your login and password you received when registering for hosting.
  
  

Step 2: Go to the “Mail” section

• In the left-hand menu, select Mail.

• You will see a list of existing mailboxes (if any have already been created).
  
  

Step 3: Add a new mailbox

• Click Create Email Address.

• Fill in the fields:

  • Email address – enter the username (e.g., info, contact, support).

  • Password – enter a secure password or click “Generate.”

  • (Optional) Set a mailbox size limit (Mailbox quota).

• Click OK or Save.
  
  

Step 4: Configure access to mail

After creating the mailbox, you can:

• Log in to webmail at a URL like https://webmail.yourdomain.com.

• Set up an email client (Thunderbird, Outlook, Gmail, etc.) using IMAP/POP3 and SMTP protocols. These details can be found in the mailbox properties.

Tips:

• For better security, enable two-factor authentication (if supported in your version of Plesk).

• Change mailbox passwords regularly.

• Check SPF, DKIM, and DMARC settings to ensure proper email delivery.
