Regularly KMail's filtering goes crazy and starts binning _all_ mail into the spam folder. The only way to go back to sanity is to remove all filters and redo them -- but then, a week later, without changing anything to the filters, it's spambox time again. Reproducible: Always

This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present? If noone confirms this bug for a Framework-based version of kmail2 (version 5.0 or later, as part of KDE Applications 15.12 or later), it gets closed in about three months.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
