My mail app in my MacBook Pro will not send emails.
My mail app in my MacBook Pro (2019) will not send emails, it just stays in the outbox or just continues to try to send them. I ran the mail connection doctor, and it says SMTP is not working, the IMAP is working fine. It has been like this for over a month. I can receive and see the emails, but I am not able to respond to them through the app. Any suggestions?
MacBook Pro 13″, macOS 10.15
