mail can't identify identity of
Hello just recently when I open mail a box comes up three times a verify certificate. Which reads mail can't verify the identity of mail.my server. I click connect , the box comes up again click connect the box comes up again click connect then it disappears. Why is this so? My server have changed some setting some time. I can't understand this recent dilemma.
Well it reads the certificate for this server is invalid but it is correct. Any suggestions Thankyou.
