Chapter 7DomainsKerio MailServer can handle multiple independent email domains for which various parameterscan be defined.In Kerio MailServer, one domain is always set as primary (the one which was created first).When other domains are added, any of the domains can be set as primary. Users log into theprimary domain with their usernames only, whereas they have to log into all other domainsusing their full email addresses. This is again best shown on an example:The domain company.com has been set as the primary domain. A user is defined in bothdomains with the name user. The user will log into the domain company.com with the nameuser, whereas for the second domain the user will have to use user@anothercompany.com asa username.Note: Users in the primary domain can also authenticate to the server using their completeemail address.This implies that unless a serious reason to set a particular domain as primary occurs, a domainwhich includes the highest number of users should be set as primary. That will makeit simpler for as many users as possible to specify their usernames when connecting to theserver.User accounts are defines separately in each domain. Therefore, domains must be have beendefined before accounts are created.7.1 Definition of DomainsDomains are defined in the Configuration → Domains section.Figure 7.1Domains63
