UTM auto delete spam based on subject, regular expression or category
I think SOPHOS UTM should have the ability to automatically delete already identified spam, using the subject line or a regular expression as the criteria. This would ease the burden on already overworked administrators! PMX already has this ability, as its policies rules are more flexible.
Or, you could categorize spam once detected. The categories could be user defined, and again, regular expressions could be used to assign the spam to the categories.
