There is a little trick to have the SPAM score displayed in each email message subject line:
webmin > servers > SpamAssassin Mail Filter > Message Modification > Prepend text to Subject: header
now change [SPAM] to [SPAM HITS]
SPAM now comes in as i.e.: [SPAM 5.5] She will be the happiest …
Makes it much easier and faster to finetune Spamassassin for the right cut off levels.
