Email Forwarding

CUIT allows you to forward your Columbia email to another address, with some limitations for security and reliability. Remember: Your email alias delivers mail to the same place as UNI@columbia.edu. You should never forward your email to your email alias!

Attention: Beginning on October 22, 2019, you will not be able to create new forwarding to email systems outside the University. Existing forwarding will continue to function until it is removed on January 7, 2020.  After January 7, 2020, UNI mail-forwarding to Columbia systems (Ex. jd1234@columbia.edu to jane.doe@barnard.edu or j_doe@nyp.org) will continue to be available.

These changes are a result of security measures implemented by many companies to prevent scammers from spoofing email from their addresses, especially financial institutions, and even some general email services like Gmail. These measures ask that email be rejected unless it comes directly from the company’s authorized servers. Many email providers including Gmail, Yahoo, and AOL, honor the request as email comes in for their users. In these cases, when columbia.edu tries to re-send email based on your UNI Mail Forwarding setup in Manage My UNI, it fails. This security feature cannot be overridden by Columbia and therefore CUIT is disallowing forwarding to external email systems.

Forwarding from UNI@columbia.edu is permitted for email addresses in the following domains. However, CUIT recommends that you have emails sent directly to these email addresses rather than forwarding to maximize the reliability of email delivery. For example, have your emails sent directly to Jane.Doe@barnard.edu rather forwarding from jd1234@columbia.edu.

Forwarding from LionMail and other Columbia G Suite systems

NOTE: Be aware that some forwarding will fail for the same reason that it is being disabled on Manage My UNI: external email systems refuse to accept forwarded email because of restrictions placed by the sender's domain.

Within your Lionmail mailbox, click on the gear icon in the upper right-hand corner of the screen and then click on Settings.

Settings is the third item from the top in the list when the gear icon is clicked in LionMail

Under the Forwarding and POP/IMAP tab, select Add a forwarding address, and fill in the email address that you wish to forward to.

Forwarding and POP/IMAP tab in LionMail Settings

Click Proceed, followed by OK to save the forwarding setting.

Click OK to finalize the saving of your forwarding address

Finally, since email forwarding is not always reliable, select Forward a copy of incoming mail to yourname@yourdomain.com and keep LionMail Mail’s copy in the inbox. Select Save Changes to confirm.

This way, if you are missing something in your forwarded mailbox that you expected to receive, you can log into LionMail and check if it is there.

FAQ

"Missing" emails like this are an unfortunate result of security measures that many companies use to prevent scammers from spoofing email from their addresses. This practice was begun by financial institutions, but is now used widely, including by some general email services like Yahoo and AOL. These measures ask that email be rejected unless it comes directly from the company’s authorized servers. Many email providers including Gmail, Yahoo, and AOL, honor the request as email comes in for their users. In these cases, when columbia.edu tries to re-send email based on your UNI Mail Forwarding setup in Manage My UNI, it fails. This security feature cannot be overridden by Columbia.

As a result, Columbia will be disallowing the ability to forward your UNI@columbia.edu to external email systems. Beginning on October 22, 2019, you will not be able to create new forwarding to email systems outside the University. Existing forwarding will continue to function until it is removed on January 7, 2020.  After January 7, 2020, UNI mail-forwarding to Columbia systems (Ex. jd1234@columbia.edu to jane.doe@barnard.edu or j_doe@nyp.org) will continue to be available.

If you currently use UNI Mail Forwarding -- or are unsure if your forwarding setup is allowed -- please refer to the table above or contact the CUIT Service Desk at (212) 854-1919.

  • Change the email address on file with the sender. Provide the sender with the email address where you read your email, that is not forwarded elsewhere.

  • Deliver to your Lionmail account. Remove the UNI Mail Forwarding in Manage My UNI and consistently monitor your LionMail account.

  • Deliver to your Exchange account. Some administrative staff are on this system, which they access using Outlook. Use UNI Mail Forwarding in Manage My UNI to forward your UNI@columbia.edu to your @adcu.columbia.edu (or @ei or @ais) address. This internal forward has been confirmed to work in all cases.
