Hi all, this may be slightly OT, but we've been blocking .emf files forever but today a user complained that we blocked their Word documents which apparently have "image1.emf" files in them and were considered a threat by amavisd due to our restricted file type policy.
I recall this being an issue from as far back as Win95/XP, but do people still consider this a real threat vector? https://en.wikipedia.org/wiki/Windows_Metafile_vulnerability
