Step 3 - Add Domains
The number of domains that can be added for your account depends on the subscription plan that you have purchased.
1. Click the 'Domains' tab on the left navigation to open the Domains area.
2. Click 'Add' and in the 'Add domain' dialog, enter a valid domain name in the 'Domain' field.
3. Enter the location of your mail-server in the 'Destination route' field. This is where CASG will send your mail after it has been processed. The default port is 25. Click 
to enter an additional route in case the primary route is unavailable for some reason.
5. Click the 'Check routes' button to get CASG to retrieve destination route information from your DNS. If the result contains the MX URL of the CASG service domain, then the DNS MX record was already updated to work withAntispam Gateway. You must enter your real MX record in the 'Destination route' field. For example mail.exampledomain.com.
6. Enter the maximum numbers of users that can be added for this domain in the 'Domain user limit' field. Leaving this setting as 'Unlimited' will allow you to add up to, but not exceed, the maximum number of users permitted by your current license.
7. Set the archive disk quota that this domain should use for storing mails. The disk space for all your domains cannot exceed the disk quota that you subscribed for.
8. Click 'Save' to add the configured domains.
If you have already configured the MX record for the domain as explained in Step 2 to the CASG service before adding it to CASG interface, then you can skip the next step and proceed to Step 5.
