Hallo!
Ich verwende auf meinem Server die Kombination aus Postfix - Amavis - Spamassassin und ClamAV.
Bis gestern hat auch alles so funktioniert wie es soll aber seither werden Spammails nicht mehr mit ****Spam**** im Betreff zugestellt sondern immer in Quarantäne verschoben, obwohl es in /etc/amavis/conf.d/20-debian-defaults anders eingestellt ist:
use strict;

# them separate, you will make the task of merging changes on these
# configuration files much simpler...
