you declared in the General network parameters form. If the organization has several
domain names, declare them to the system to optimize email processing. Email addresses that
belong to domains declared to the system do not need external DNS queries.
To declare a domain name to the system:
1. Select the Service management > Email > SMTP > Domain names menu.
2. Click Add.
This opens a Declaration of the domain names managed by the appliance form.
3. Enter the new domain name.
4. For the Transport option:
• Select Local if the mail server manages all emails belonging to this domain.
• Select Via SMTP if several email servers manage emails belonging to this domain.
When such an email is to be processed, the mail server tries first to process it from its
own tables. If the email address is not found there, the message is sent to a next mail
server via SMTP. You must specify this next mail server by its Server name and
Login/Password if required.
Several mail servers can be chained this way.
5. Click OK.
Once the new domain name is declared, you can create new email addresses for each user
who needs an email address with this domain name.
Example below shows the list of domain names after a second domain name has been
created.
