After using CF i stopped receiving emails via POP3 through gmail. Webmail is working.
I didn’t add any DNS records upon setup and tried to work with the existing ones following the email troubleshooting tips. But I have more records (eg: AAAA) and there still might be a misconfiguration somewhere i can’t firgure out. I hope someone here can spot the issue right away!
Gmail is configured correctly but i just found out that after my latest DNS record change i had to enter the email password of the POP3 accounts again. Now it works with the records i have provided above. Thanks for checking and trying to help, sdayman!
