This may just be an issue of bug 81753 (or other improve offline panel bugs). It's all gotten confusing and I admit I haven't been following the issue closely... so just in case, here's a separate bug: Using july 2 commercial 0.9.2 branch builds, all platforms. The "Disk Space" limit download pref doesn't stick for accounts other than POP (related bug 81494). Spec still shows it should be there, but it doesn't stick. 1. Go to Edit|Account Settings|Offline&DiskSpace for an account of type IMAP, WebMail or News/NNTP. 2. Click/checkmark to enable the option "Do not download messages locally that are larger than N kb". OK the account settings dialog to confirm change. 3. Open the account settings dialog again and look at the option for that same account again -- it is disabled. Result: change to enable the pref doesn't stick.
