Gnubiff is excellent, but having a LOT of spam these
days is not nice.
80% of spam that got trough of server's spamfilters can
be identified by an quick glance.
On the other hand seen it, and having to start an
full-featured client program is ineffective IMHO.
If I see spam I can kill spam. - that's what i'd like.
In fact, tere is an app that does that - SaveMyModem,
but author is't speeding towards applets and GTK2 <or
multithreading for that matter>.
