as of yesterday Apple mail will not download mail from two of my accounts with Gmail. It keeps asking for password which i keep entering but with no success. I can go straight to gmail and access my account using same password. but not through Apple mail. On one occasion a box popped up saying that the certificate of authentication was not valid and that I may be being directed to another site???? I have other email addresses that it is still downloading fine, but they aren't with Gmail. I also download my mail to my i-pod touch and that is still working fine. Someone please help!!!
