7.1  Initial settings

All basic settings for email domains can be found in the Kerio MailServer's administration interface, section Configurations → Domains (see figure 7.1  Domains):

Setting server's Internet name

To make email deliverable to mail domains, Kerio MailServer requires specification of a DNS name of the host where the server is running (typically, it is the name of the host complemented with the primary domain name — this server name is generated automatically by the installation wizard).

Domains are defined in the Configuration → Domains section. Server names are used for server identification while establishing SMTP traffic.

Upon initializing SMTP communication, the EHLO command is used for retrieving reverse DNS record. The server that communicates with Kerio MailServer can perform checks of the reverse DNS record.

Warning

If Kerio MailServer is running behind NAT, enter the Internet hostname that can be converted to the IP address of the sending server, i.e. the internet hostname of the firewall.

To set the hostname, follow these guidelines:

  1. In the administration interface, go to Configuration → Domains.

  2. Use the Internet hostname textfield in the tab header to enter DNS name.

Sharing public folders across domains

Basic settings of the domain system in Kerio MailServer include also the option of[3] sharing of public folders across all created domains or creating of public folders separately for each folder. This can be set in Configuration → Domains by the Advanced button (see figure 7.2  Advanced domain settings).

To read more on public folders and their settings, refer to chapter 26  Folder Administration.



[3] Public folders are folders which can be read by any users within the domain or any users in Kerio MailServer. They are created and managed by a user with administration rights for public folders. Public folders can be helpful for sharing contacts or calendar with company events across the company, for example.
