Service Restored at 8:45 a.m.: This issue has been addressed, and Yahoo is no longer blocking email from @colorado.edu accounts.
Service Issue Reported at 11:47 a.m.: A campus email account was recently targeted by malicious email and producing spam. While OIT has addressed this specific situation, when this occurs, Internet Service Providers often temporarily block email for security purposes. Yahoo is currently blocking email sent from @colorado.edu to @yahoo.com or @ymail.com addresses. As a result, campus email sent to these addresses will be delayed. OIT is working to address the situation, and more information will be posted here as it becomes available.
