Each AWS regional production data center has now been set up to use a more local mail relay instead of redirecting to the United States.

The following table lists the email relays that should be used in the customers' SPF records where applicable.

AWS Regional Production Data Center Email Relay
AWS (default US) - B1P mail-relay-aws.blackboard.com
AWS (us-east-1 US) - V5P mail-relay-aws-us-east-1.blackboard.com aliases to

mail-relay1-cse1.blackboard.com

or

mail-relay6-cse1.blackboard.com

AWS (us-west-1 US) - O1Q mail-relay-aws-us-west-1.blackboard.com aliases to

mail-relay1-cse1.blackboard.com

or

mail-relay6-cse1.blackboard.com

AWS (ap-southeast SIN) - Z1P mail-relay-aws-ap-southeast.blackboard.com aliases to

mail-relay1-sin1.blackboard.com

or

mail-relay6-sin1.blackboard.com

AWS (ap-southeast-2 AUS) - S2P mail-relay-aws-ap-southeast-2.blackboard.com aliases to

mail-relay1-syd1.blackboard.com

or

mail-relay6-syd1.blackboard.com

AWS (eu-central-1 FRA) - E3P mail-relay-aws-eu-central-1.blackboard.com aliases to

mail-relay1-fra4.blackboard.com

or

mail-relay6-fra4.blackboard.com

Customers should add a:{mail relay from above table} to their SPF (or SPR) record. If that makes their SPF record too long or have too many DNS lookups (a maximum of 10 are allowed) then they can use ip4:{ip address of relay from above list}. Please note that most of the data centers use two relays in rotation so both are needed.

To connect, either edit that file and remove any references to the servers and try to connect again, or use the following command: ssh-keygen  -R  sftp02-na.blackboardopenlms.com


AWS Inbound

AWS utilizes dynamic IP ranges across multiple availability zones for stability reasons. As a result, we use CNAME DNS records for your Moodle sites and can't accurately guarantee the IP address for your site won't change. If you require whitelisting of your site, AWS recommends utilizing whitelist based on DNS resolution. This will ensure continued access in the event of an IP change.
