[help] How to add more multi mailbox in current Zimbra single server

[littlekiss]

Hi everybody,
I have the following problem that needs help from everyone. Please help me because I am an amateur.

-Now I have a server that installs Zimbra Mail system. Every user uses a mailbox with a company domain. The need now for administrators is that I have to add multiple mailboxes to that user and add another domain on that mailbox.

Please help me on the problem or have documentation to help me.

Version Zimbra mail: 7.2.4
CentOS 6.10

Thanks everybody
