I have used email forwarding before and it worked!
However, recently I registered a professional email with Gsuite and other two forwarding emails such as firstname.lastname@example.org,email@example.com and firstname.lastname@example.org stopped working. When you try to send email it bounces back and says that it is undeliverable. What is also very strange is when I go to store/domains/manage domains I cannot find anymore the window to enter forwarding emails. Or maybe I'm looking at the wrong section? Please advise how I can fix this?
