Virtual gateways Delivery Limits Domain-Based Limits Domain-Based Routing Global Unsubscribe 4-10 Cisco IronPort AsyncOS 7.6 for Email Configuration Guide Chapter 4 Understanding the Email Pipeline The Cisco IronPort Virtual Gateway technology enables users to separate the Cisco IronPort appliance into multiple Virtual Gateway addresses from which to send and receive email. Each Virtual Gateway address is given a distinct IP address, hostname and domain, and email delivery queue. For more information, see “Using Virtual Gateway Technology” in the “Configuring Routing and Delivery Features” chapter of the Cisco IronPort AsyncOS for Email Advanced Configuration Guide. Use the deliveryconfig command to set limits on delivery, based on which IP interface to use when delivering and the maximum number of concurrent connections the appliance makes for outbound message delivery. For more information, see “Set Email Delivery Parameters” in the “Configuring Routing and Delivery Features” chapter of the Cisco IronPort AsyncOS for Email Advanced Configuration Guide. For each domain, you can assign a maximum number of connections and recipients that will never be exceeded by the system in a given time period. This “good neighbor” table is defined through the Mail Policies > Destination Controls page (or the destconfig command). For more information, see “Controlling Email Delivery” in the “Configuring Routing and Delivery Features” chapter in the Cisco IronPort AsyncOS for Email Advanced Configuration Guide. Use the Network > SMTP Routes page (or the smtproutes command) to redirect all email for a particular domain to a specific mail exchange (MX) host, without rewriting the envelope recipient. For more information, see “Routing Email for Local Domains” in the “Configuring Routing and Delivery Features” chapter of the Cisco IronPort AsyncOS for Email Advanced Configuration Guide. Use Global Unsubscribe to ensure that specific recipients, recipient domains, or IP addresses never receive messages from the Cisco IronPort appliance. If Global Unsubscribe is enabled, the system will check all recipient addresses against a list of “globally unsubscribed” users, domains, email addresses, and IP Addresses. Matching emails are not sent. For more information, see “Using Global Unsubscribe” in the “Configuring Routing and Delivery Features” chapter of the Cisco IronPort AsyncOS for Email Advanced Configuration Guide. OL-25136-01
Chapter 4 Understanding the Email Pipeline Bounce Limits OL-25136-01 You use the Network > Bounce Profiles page (or the bounceconfig command) to configure how Cisco IronPort AsyncOS handles hard and soft conversational bounces for each listener you create. You create bounce profiles and then apply profiles to each listener using the Network > Listeners page (or the listenerconfig command). You can also assign bounce profiles to specific messages using message filters. For more information about bounce profiles, see “Directing Bounced Email” in the “Configuring Routing and Delivery Features” chapter of the Cisco IronPort AsyncOS for Email Advanced Configuration Guide.
