Gmail Security Certificate problem
I have Mail setup to access three Gmail via IMAP (I was using POP until a week ago). Whe ntrying to check messages (sinc, I guess), I get the following problem message (for the three accounts) in regards to a "security certificate" being POP when I trying to use IMAP. Not sure what is going here... I checked my Gmail settings 3 times and all is set for IMAP from that end. Obviously I haven't been able to access messages from Mail since then. Suggestions?
