A lot of my spam lately has had an ISO encoded subject line, like: =?iso-8859-1?B?T2ZmaWNlIHNvZnR3YXJlIC0gNzUlIE9GRg==?=
Since none of my friends ever use ISO encoded subject lines, I wanted to create a rule to flags those messages. However, everything I've found indicates that Spamassassin tests the decoded subject line, not the raw subject line. I've tried: header SUBJECT_ISO_ENCODED Subject =~ /=?iso-8859/i but that doesn't seem to work. Is there any way I can run a rule on the raw header to detect whether or not it's encoded? If so, could you please show me how? TIA. Joseph D. Wagner
