UBC Interchange Mail Relays blocked by Hotmail/Live June 21, 2010 12:55

On June 21st 2010 at approximately 8:00am, Hotmail and Live.com servers began blocking e-mail from 4 of the 8 UBC mail relays. As a result, only about half of the messages destined for these services are being delivered successfully. UBC IT staff submitted the appropriate removal form this morning and are awaiting action from Microsoft. In the interim, the e-mail team is investigating a workaround to leverage the other mail relays for delivery to Hotmail and Live.com.

The Interchange service and any campus e-mail servers that send e-mail through the mail relays will be affected by this blockage. The UBC Exchange e-mail service is not impacted as it does not use the UBC Mail Relays to deliver message.
