Version: (using KDE KDE 3.5.7) I can just guess from the effects I get, that KMail works in single line mode. Please switch to multiline -- nothing that could be done in SL cannot be done in ML, but there are regexps in ML that couldn't be done in SL. Or provide extra switch for ML. In other words I would like this would work: AssignedTo([^\n]*)\n\n\n$
Thank you for your feature request. Kmail1 is currently unmaintained so we are closing all wishes. Please feel free to reopen a feature request for Kmail2 if it has not already been implemented. Thank you for your understanding.
Instead of creating a new feature request, please confirm here if the wishlist is still valid for kmail2.
