Configure the domains that IMSA requires to relay email messages to mail servers.
To prevent spammers from using the IMSA MTA as a relay for spam, configure relay control. You will add the mail domains on your network to the Relay Domains list. When IMSA receives an email message, it looks at the final destination of the email and compares it to this list. IMSA discards the message under the following circumstances:
The destination domain is not in this list
The parent domain of the destination domain is not in this list
The host is not on the Permitted Senders of Relayed Mail list
To configure relay domains:
You can configure relay domains by adding domains one at a time or importing a file containing a list of domain names.
To add domain names individually
Under Add Domain, type the name of an email domain on your network; for example, mydomain.com.
To add the domain to the list, click >>. To remove a domain, click it in the list, and then click <<.
To import a list of domain names
Click Import From File.
Type the path and name of the import file or click Browse to select from the directory.

When IMSA receives an email message addressed to a certain domain, it passes the email to another SMTP server for delivery. If the SMTP server cannot resolve the IP address of the destination computer, IMSA needs access to a DNS server to resolve the IP address. Use this screen to specify a list of SMTP server domains and their corresponding SMTP servers.
To configure domain-based delivery
