Pop - gmail - mail no longer downloading after 10.5.8 update

Question

I don't know if it's related to the update - and I think I also updated safari (which I never use) but overnight my mail program has stopped downloading new mail from my Gmail account, which has always worked without a hitch.
The connection doctor says all is good - green lights all around.
And when I view the activity monitor while it's looking for new mail, it says 'connecting to...' and then 'sending password' and then nothing. It just ends, no new email, no error, no nothing.
Anyone??????

Answer 1

Ok, so I got mine working by deleting my Mail preferences from ~/Library/Preferences/com.apple.mail.plist. Just move that file to your desktop while Mail is quit. You can always put it back if you like.
The down side is that you lose your accounts and have to set them up again, but all your mailboxes and downloaded emails should be reconnected fine. The preferences file contains the information about the accounts, but not the mail itself.
I tried restoring a backup copy of my preferences file, but as others have mentioned, each time I quit and restart Mail, my accounts were lost again and it asked me to set them up. The only way I found to prevent this was to get move the preferences file aside. Now it quits and restarts without a problem.
Hope that helps. Not ideal, but you can at least get back up and running.
