Here is a screenshot of connection doctor showing the RED DOT and the log file showing successful authentication. What is really odd, Connection Doctor shows a successful connection in the log file, but shows a RED DOT for the connection status to IMAP. Mail does not seem to want to keep the setting. When I go back and check my settings, I see the box is unchecked.Īs you can see from above photos, I have Use TLS/SSL not selected and the Allow insecure authentication has been unchecked by the system. When, I try to save, I get the cannot validate error: I set the "Allow insecure Authentication", but it does not keep it.īelow is screenshot showing I have checked the correct boxes.
It seems to only be happening to my High Sierra system. This did work in ElCapitan and is working on three different computers.
#MAIL APP FOR MAC SIERRA NOT SENDING EMAILS INSTALL#
Only, I did a clean install of High Sierra and am trying to configure Mail for my mail account.
