macOs10.13.6
I can not either receive my mail nor ail on my Macbook air (macOS 10.13.6) since 2 days ago.
It showed Authorization Error, Error 400; Invalid _request.
I went to mail > preference > serve setting but could not find smtp.gmail.com for out going mail.
When I reviewed logs, it showed quit on the bottom.
Does it mean I deleted stmp.gmail.com?
I tried to edit stmp.gmail.com but it did not work.
I would appreciate it if you could help me
MacBook Air 13″, macOS 10.13
