@Matt: How can I find out if I can downgrade when there's no change log for 7978 available any more?
We strongly recommend avoiding any/all downgrades. While I am happy to hear your IMAP interface is working as expected post-downgrade, I recommend other users refrain from doing so to avoid further issues.
