On Aug. 1, [U]Tech will make necessary security changes to smtp.case.edu which will improve deliverability of authentic case.edu mail. The change involves removing the legacy authentication of all email flowing through the CWRU mail system via smtp.case.edu by no longer automatically applying a DKIM signature. DKIM (DomainKeys Identified Mail) is a standard email authentication method that adds a digital signature to outgoing messages.
Email clients and applications that have their SMTP service still configured to use smtp.case.edu will no longer benefit from having their email authenticated by default through the CWRU mail system servers. Industry-wide, it is now expected that every system sending for a given email address is properly authenticating those messages to ensure their integrity and is not being impersonated.
If you are using your CWRU NetID with an email client besides webmail, it is recommended that you follow the suggestions as outlined on item #6 on the Google Mail Authentication Change FAQ | University Technology webpage to configure the client’s SMTP settings. If you have already made the recommended change, or are using CWRU webmail.case.edu, there is nothing further you need to do.
Third-party vendors who are configured to use smtp.case.edu to send email are expected to provide their own email authentication after Aug. 1 to ensure deliverability. If you have contracted with a third-party vendor and have not already done so, please follow the recommendations as outlined on the Google Mail Authentication Change FAQ | University Technology webpage to ensure your vendor is properly configured to send mail on behalf of CWRU.
