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?

Check & see if you still have gMail POP as a server in Mail>Preferences>Account Information tab>Outgoing SMTP Servers>Edit Server List

Not certain, but this can fix myriad Mail problems...


Safe Boot from the HD, (holding Shift key down at bootup), it will try to repair your Disk Directory while the spinning radian is happening, so let it go, run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, then move this folder & file to the Desktop.


Move this Folder to the Desktop...


/Users/YourUserName/Library/Caches/Mail/


Move this file to the Desktop...


/Users/YourUserName/Library/Mail/Envelope Index


Reboot.


If that doesn't do it and you can afford to redo all your Rules, try these & reboot...


/Users/YourUserName/Library/Mail/MessageRules.plist


/Users/YourUserName/Library/Mail/MessageRules.plist.backup


Note, in 10.5 & up /Users/YourUserName/Library/Caches/Mail/ may or may not exist.
