"Cannot Send Mail" Even to myself

Every email I tried to reply to had the message, "Cannot Send Mail. The Sender Address was Invalid." I even tried sending to myself with my spectrum email address and got the same message. I also entered every address I tried to reply to in "Safe Senders". What gives?

    Go into the email account settings and make sure the username, not to be confused with any other name or address in settings, is your full email address rather than just the id. part thereof regardless of whether the latter used to work.

    @HT_Greenfield - It is the exact same. Using the ports they recommend as well.

    Hello @felyne,

    Sorry to hear that you're unable to send emails, I'm happy to help! Have you tried logging into Webmail to send a message to yourself?
