Rejected e-mails from Telenor domains
NHH’s security systems has rejected e-mails from certain Telenor domains, including @telnor.com and @online.no, for a while due to registered attempts to send very large quantities of email from these domains.
NHH has security systems tied to incoming email.
These systems rejected mail from the mentioned domains when the traffic suddenly surged.
The traffic is now back to a more normal level, and the systems have been reopened for mail from Telenor.
