Starting yesterday afternoon sometime, my IMAP access to Gmail from Apple Mail 3.1 has been broken. The IMAP account won’t go online. I can’t find any mention of this sort of problem on the internet. My Gmail works fine from their web interface.
I keep getting the following error:
2.74 NO [ALERT] Lockdown in sector 4 (Failure)
Here’s a sample log of what I’m seeing during the IMAP connection:

Can anyone help me fix this? I presume it’s a problem on Gmail’s end, but I don’t know how to confirm that.
