James Ervin, wanting to use a backreference from a regexp, writes:

What you want is procmail's MATCH operator: "\/". When inserted in a
regular expression, everything following the the operator is assigned to
the $MATCH variable. So two changes are requred to your recipe above.
Insert \/ before the \. of the filename extension:
* ^Content-(Type|Disposition):.*name=.*\/\.(exe|com|zip|vbs|shs|hta|scr|chm)
And then use $MATCH when inserting the custom header:
| formail -I "X-VIRUSWARNING: This file had a $MATCH attachment"
