Outgoing Mail not working from my MacBook Pro
I have a Macbook Pro (late 2013) with macOS High Sierra. My outgoing mail stopped working. I can still receive emails, just not send them. I keep getting timed out, then a message telling me to select a different outgoing mail server but I don't know how to fix. I even tried mail connection doctor but that didn't work either. Can anyone help?
MacBook Pro 13", macOS 10.14
