Email Routing: Configure Mail Routing

The system allows you to designate a series of next hops for inbound (forwarded) mail destined for your organization’s mail system, and outbound mail during an activation of Email Continuity. Before changing these settings, see the sections on mail routing: For more information refer to Inbound Mail Routing Requirements for Email Continuity. and For more information refer to Mail Routing — Outbound During Activation..

NOTE

An audit trail is provided for all changes made to mail routing, including event, actor and day/time information.

By default, Continuity will resolve the email it receives using public MX records. However, if your organization would like to have Continuity send the email it receives to specific destination MTAs, you can specify those MTAs within the Continuity Admin Console. Additionally, if your organization uses a third-party gateway to filter your email prior to being relayed to your primary mail system, it is required that you identify specific destination MTAs within your onsite messaging solution in order to prevent mail looping.

If the destination MTA defined within the Continuity Admin Console is unavailable to accept email from Continuity, our systems are designed to hold and retry delivery for up to 30 days, or until the defined host resume accepting email.

NOTE

When you configure the system to use hostnames instead of MX records, it can take up to 10 minutes for the changes to take effect.

TIP

Though the routing features accept both IP addresses and hostnames, hostnames provide greater flexibility and are preferred.

CAUTION

After making changes to routing for inbound or outbound mail routing or delivery, verify the changes by performing a test activation. Incorrect or invalid settings can result in delayed, bounced or lost messages.
