To send emails from firstname.lastname@example.org in Gmail
*** The first step must be to opt-in your CNET ID to authsmtp.uchicago.edu by sending e-mail to email@example.com ***
* In Gmail, click the gear icon, click on "Settings", then go to the "Accounts and Import" tab.
* In the "Send mail as" section, click the link for adding a new email address.
* After specifying the email address "firstname.lastname@example.org", here is the information to enter:
- use the SMTP server "authsmtp.uchicago.edu"
- use port 465
- use SSL, not TLS
- use your CNet ID username and password
Please be aware that forwarding your e-mail will break DMARC authentication, which so far seems to be employed by NSF and orau.org. You should give such organizations the e-mail that is your final destination. E.g., if you are forwarding to gmail, give those organizations your gmail address. Another alternative would be to use POP to transfer your departmental e-mail to gmail instead of forwarding.
