Use the WebAdmin Interface to open the General page in the Settings realm:
In this field you should enter the name that the CommuniGate Pro Server will interpret as its own Main Domain Name. All mail addressed to that domain will be treated as local, and (in the simplest case) that mail will be stored in local Account Mailboxes. Initially, this field contains the server computer name that CommuniGate Pro retrieves from the OS. If this names looks like host12345hh.company.com, you should change it to the name of the domain this Server should process.
Note: unless you create additional Domains ONLY the E-mail Messages and Signals directed to addresses in the Main Domain will be processed as local. If the Main Domain Name is entered as company.com, then Messages to mail.company.com or Signals to sip.company.com will not be processed as local, and if such a Message or Signal is received, the Server will try to deliver it to the mail.company.com or the sip.company.com system over the network. If the DNS record for mail.company.com or sip.company.com points to the same Server computer, the mail loop or signal loop error will be detected, and the Message or Signal will be rejected.
If your Server should serve several domain names, enter the additional domain names as Main Domain Aliases (if those domain names should be "mapped" to the Main Domain), or create additional ("secondary") Domains.
Your Server should the company.com and client1.com domains. These domain names have their DNS MX-records and SIP SRV-records pointing to the server.company.com and server.client1.com A-records, and these A-records point to IP Address(es) assigned to your CommuniGate Pro Server System.
Use this setting to specify what kind of information the Server kernel module should put in the Server Log. Usually you should use the Major (message transfer reports) level.
