I downloaded El Capitan today over Mavericks with no problems except for one. In Mail I can send mail, but I can only receive mail now if I go to Mail pref's-Accounts-Advanced, and check the box for authorizing insecure authentication. When checked I can receive email, when not checked I can send but not receive and the connection doctor shows: charter SMTP, connected to server, IMAP connection failed connection. I have called my provider and went thru my settings and it does not seem to be their problem.
Any suggestions or ideas?
Thank you.
