Email Aliases Administration

E-mail aliases explained

An e-mail alias allow to add another name to an existing e-mail address. Like any other e-mail address, it is composed by a username (e.g., john.doe) and a domain (e.g., separated by a

Aliases prove useful in a number of cases, including:

  • To subscribe to mailing lists or newsletters without using your real e-mail address for privacy reasons

  • To make the management of incoming mail easier by defining suitable filters

  • In company environments, aliases are often used to assign an e-mail address to a role and not to a person. For example, an alias forwards email to the head of the IT department: when the person in charge is replaced, you just need to point the alias to the e-mail address of the new person.

The main difference between an alias and a regular e-mail address is that an alias does not occupy any space on the server to store the e-mail, because all e-mails sent to the alias will be forwarded to the user’s e-mail address. Therefore, deleting an alias will not impact the existing user’s e-mails.

Carbonio, like any other e-mail server, provides email aliases and allows the zextras user to define and remove them using the CLI. However, there is no method to transfer an alias from one user to another: you must first delete the alias from the old user before assigning it to the new one.

Add an alias to an account

zextras$ carbonio prov aaa

This command adds alias to user


aaa is the short form of addAccountAlias.

Remove an alias from an account

zextras$ carbonio prov raa

This command removes alias from user


raa is the short form of removeAccountAlias.
