Previous Description (August 26, 2020 10:11):

On Thursday August 27th at 7am, the on campus email relay service - extmail.queensu.ca will be moving to the Barracuda Message Gateway - Mail.queensu.ca.

Going forward, mail.queensu.ca will receive and route all campus email. All messages directed through extmail.queensu.ca will continue to function, but the underlying physical mail relay will be changed. Any services that use the IP address 130.15.126.71 to send email should update their settings to either mail.queensu.ca or if they must use an IP address: 130.15.126.73. The extmail server will not be turned off until legitimate email traffic has ceased to pass through it.

If email delivery issues arise please report immediately to the IT Services Support Centre.
