RESOLVED: Yahoo DMARC impacting several campus services
Service Restored

This is resolved.


ITS has identified probable disruption of email communications in the following services due to Yahoo’s implementation of their new DMARC, or Domain-based Message Authentication, Reporting & Conformance policy:

Services with confirmed Impact
•      UT Lists
•      Blackboard
Services with probable Impact
•      Group Messaging
Services with potential Impact
•      Canvas

Impacted populations have been identified as recipients with @yahoo.com domains, or Yahoo managed domains such as @sbcglobal.net, @swbell, @att.net, and @comcast.net.  Senders from these domains may also see bounces from @hotmail.com, @msn.com, @live.com, and @google.com (and any Google Apps addresses, including UTMail users).

Until such a time as Yahoo changes this policy, we suggest using one of the email accounts sponsored by The University of Texas at Austin, changing official email addresses, and changing addresses in UT Lists.  Sponsored Accounts for students include UTmail.  Sponsored accounts for faculty and staff include AEMS and Office 365, as decided by your department.
