It is possible to define any number of virtual domains (aliases) for the each email domain. Virtual domains are alternative names (aliases) for a particular domain. Names of the virtual domains can be specified in the Aliases section. Email addresses within the virtual domains are identical (delivery is performed to the identical mailboxes). If this option is used, individual user accounts can belong to multiple domains.
Usage of domain aliases will be better understood through the following example:
A company uses two domains: company.us
and company.com
. The company.us
domain is was set as a mail domain in Kerio MailServer. Email addresses of the domain users are user@company.us
. If we create the company.com
domain alias for the company.us
domain, it is also possible to use the user@company.com
for identical users. It does not matter, whether the user@company.us
or the user@company.com
is used. In both cases, the mail is delivered to the same user.
Unless this is a local alias (virtual domain), corresponding MX records must be defined in DNS for each of such domains. A simple definition of the domain as an alias of another domain does not make the alias exist in the Internet.
Domain aliases can be used only for email delivery. It is not possible to use them for user authentication at Kerio MailServer or to view the Free/Busy server. Domain aliases cannot be used for administration purposes.
To set a domain alias in Kerio MailServer, follow these guidelines:
Open the administration interface and go to
.Open settings of the domain which the alias will be set for and go to the Aliases tab.
To set a new alias, click on 7.7 Domain settings — equivalent domains (aliases)).
