That works!  I'll give it a small score to fend off those FPs.  Maybe
combine it with a another test like:
header SILD             Subject =~ /Sildenafil Citrate/i
:)  Thanks!

It translates it.  Try

  header MK_CHARSET_IN_SUBJECT Subject:raw =~ /ISO\-8859/i

but that will FP quite a lot on non-english words.
or, of course,

  header SILD           Subject =~ /Sildenafil Citrate/i

;)
