For about a year I forwarded email from a .edu email address (the university uses Gmail interface) to another gmail. It was a bit tricky to set up- just forwarding didn't work, I think I had to also enable IMAP from the sending email.
Now, I want to NOT forward. I disabled POP and IMAP in both accounts. The receiving email doesn't have the sending email listed in the Accounts and Imports tab. The sending email doesn't have the receiving email listed under Forwarding addresses. I even checked other linked accounts to make sure the emails aren't being sent from the .edu addresses to another account and THEN to the receiving account. I have tried and checked these things over 3 weeks now, so should be plenty of time for any potential delay. Yet the emails keep coming in. Any suggestions?
