Bellsouth.net email "550 Request failed; Mailbox unavailable"??
I have had a bellsouth.net account for 20+ years. Starting this week, every email I have tried to send from my laptop from my bellsouth account has been returned as undeliverable with this 550 error code.
Does anyone know how to fix this problem?
Oddly, I can reply/ send emails from my phone through this same account.
