Hello, how can I set Thunderbird to always hide emails that have been marked as deleted in an IMAP account? There is a dropdown "View" which can be set to "Not deleted", which does the job. But this dropdown resets as soon as you select a new folder, which of course makes it impractical to use. How can I a) set "Not deleted" as default for all folders and b) make Thunderbird instantly hide a message I have just marked as deleted? (Even if the dropdown is already set to "not deleted", a message newly deleted is still just stricken out, but still listed until I select "not deleted" again.) To make it very clear: Thunderbird's principal behaviour in marking-as-deleted with IMAP is correct and expected. It's just the view filter that doesn't work as required. Regards
