See the article “How to point a domain to hosting”?
1. Log in to the hosting control panel using your agreement number and password.
2. Go to the Mail (Почта) section.
3. Click Create new mailbox (Создать новую почту) in the top-right corner.

4. In the Select Domain (Выберите домен) section, choose a domain from the list of domains registered under your agreement, or enter a domain name manually by selecting New Domain (Новый домен). Then specify the mailbox name and password, and click Create (Создать).

5. Additional mailboxes are created in the same way. When creating a mailbox, you must select the domain under which it will operate.

1. In the hosting control panel, go to Mail (Почта) → your_domain → Mailboxes (Почтовые ящики), then click the mailbox name to open its settings. On the settings page, you can add a short description (comment), add aliases, set a disk space quota (limit), and change the current mailbox password.

2. In the Aliases (Синонимы) section, you can add an email alias. For example, the mailbox mail@example.com has the alias mail1@example.com. As a result, emails sent to both mail@example.com and mail1@example.com will be delivered to the same mailbox.

3. A mailbox user can change their password independently in the webmail interface at mail.nic.ru under Settings (Настройки) → Password (Пароль).

4. Click Import (Импортировать).

5. Click Choose files (Выбрать файлы) and select the contacts file you want to import. In the Group assignment during import option, select the desired import method or leave None selected.
If necessary, enable Replace entire address book. Then click Import (Импортировать).

6. If the import is successful, you will see a message with the list of imported contacts. To continue working in Roundcube, click Cancel (Отмена).

An import error may occur when uploading a .CSV contacts file.
CSV files are created and edited in spreadsheet editors. In CSV files, data is stored as text separated by commas rather than in visible columns. The text consists of fields that must appear in a strict order. An import error occurs if the contact file structure (field order) is incorrect or if the file is empty.
