Email advice and testing

Our spam-relay tester and notification system will test your mail server and report unauthorised relays.

Since this service was introduced over a decade ago, we have seen a steady decline in the number of unauthorised mail relays on the Janet network - a positive step towards reducing unsolicited email. As a result, the email advice and testing service will be discontinued on 31 July 2023, allowing Jisc to prioritise resources to meet the needs of the sector.

If you have any questions regarding the closure of this service, please contact or talk to your Jisc relationship manager.

The test involves connecting to a mailer and relaying a series of individual messages through it, just as the bulk mailers do in preparation for a spam run.

The system will scan your servers on request, however, we can also systematically run the test on Janet-connected systems which have been reported as relaying spam.
