detect X-DCC headers ?

Hi, all,

I'm trying to write my first milter, to remove different X- headers in a
mail.   I use smfi_chgheader without problem for fixed X- headers.
However, since the brand in X-DCC varies, I've no idea about how to
handle it.  Would anyone pls help, or shall I ask in milter groups
instead?

I'm new to DCC and milter.  Sorry for the newbie question.

Thanks a lot.
