Hi everyone,

A user of ours was just emailed a zip file containing some SDG files,
which are apparently graphics files. For some reason, SDG is classed as
an executable file and therefore disallowed by the filename rules. Should
I tell the system to allow SDG files or does this really represent a
security issue?
