I have this problem as well. VPN on, can't send. VPN off, sends just fine. I had an issue with using COX email at my work early in 2020, and best I could find out, was that COX requires a "reverse DNS" lookup from the server that is sending the mail, and our IT folks had turned off that function with our servers. After much complaining, the IT folks at work eventually got around to make that happen again, and then mail started sending once more. Perhaps when on VPN (like at home), this Reverse DNS doesn't happen?
