http://bugs.kde.org/show_bug.cgi?id=46826#c6 Spamassissian also plugins into quite a few email clients. Luc stability is a issue. Wine does from time to time break applications. Yes it might take a little longer to setup something like Spamassiassian or one of the other native Linux spamfilters but they are 100 percent stable. Yes they should have better GUI's for config them.
