Email provider not working after upgrade

[dwestland]

I upgraded next-auth 3 to next-auth 4.3.4. Followed the Upgrade Guide and Email for v4 from the documentation and updated the database. The GitHub Provider and Google Provider work fine as they did before the upgrade. However, the Email Provider does not work. When I "Sign in with Email", I get a message on screen "The e-mail could not be sent". I am running on localhost and getting the following errors from the Next console: SEND_VERIFICATION_EMAIL_ERROR Message failed: 550 The from address does not match a verified Sender Identity. Mail cannot be sent until this error is resolved. SIGNIN_EMAIL_ERROR

When I revert back to next-auth 3, The Email Provider works fine.
