For each domain in your organization, you must specify the mail server IP address or host name that your inbound mail is delivered to after it has been filtered. If you have multiple mail server IP addresses, you can configure these as multiple-SMTP profiles on the Company tab.
Similar to adding outbound IP addresses for your entire company, you can also specify outbound IP addresses for individual domains. All email sent through these outbound IP addresses will be filtered by the outbound Forefront Online Protection for Exchange (FOPE) service.
