So then to strip alot of file extentions, but allow eml files and
have them mangled, I should exclude .eml from /etc/procmail/stripped
rather than from MANGLE_EXTENSIONS?

Even if the .eml is mangled?

I guess my above mangling question applies here also. But, are you
saying if a .rtf file comes along, the Sanitizer checks to see if
it is really a .DOC format then does the macro scan (if enabled)
but if it fails to be a .DOC, goes ahead and mangles according to
