        We put the  "SHELL=/bin/bash" here.

        If you work only on "Content-type: ..." you miss the uucode
        format.

        Procmail ignores UPcase by default:
's/\(name=".*\.vbs\)"/\1.txt"/'

        What about this extra "{"?   Did you try the script before?

        In my old procmailrc I did the same (I trust our antivirus now)
        The recipe:

EXTN="vbs|wsf|eml|shs|exe|nws|chm|pif|vbe|hta|scr|com|lnk"
:0 Bfw:
*$ ^([  ]+.*name[  ]*=|begin[  ]+[0-9]+[  ]+|Content-).*\/[.](${EXTN})\>
*$ MATCH ?? ()\/(${EXTN})
| sed -e            "/^Content-.*\.$MATCH\>/s/\.$MATCH\>/_txt/g" \
          -e             "/^begin\>.*\.$MATCH\>/s/\.$MATCH\>/_txt/g" \
          -e "/^.*name[  ]*=[  ]*\".*\.$MATCH\>/s/\.$MATCH\>/_txt/g"

        NOTE:  The "[  ]"  is "[ + space + tab + ]"
