Mail exchange on a virtual server is set up in the Domains –> Mail domains section by pressing the Create button.
After creating an e-mail domain on your user’s behalf, you will perform all the operations on his behalf in the future as well. So every time you wish to enter the e-mail domain, you’ll have to follow the link for the domain name in the Mail Domains section and press Enter key.
It's possible to have many e-mail domains and each of them belongs to a certain user.
After entering, you can select a required subsection in the Mail section and work with your mail.
