I found this thread while look for a way to block certain
attachments.
I used the recipe and as long as the user sends from
netscape mail or pine it works, but any user sending the
same attachment from outlook express or outlook, the mail
gets through. Is there something else that needs to be done
to make sure all email programs get filtered out with those
types of attachments?

here's a recipe, all credits go to Philip Guenther, I've

extensions I need to filter to his regexp.
# The regexp for matching whitespace in the embedded header

ws = '[ ]*($[ ]+)*'

anything

character)

dotstar = '.*($[ ].*)*'
# A single double-quote. For use in variable expanded
regexps to
# avoid problems related to how procmail implements the
variable
# expansion
dq = '"'
# Any condition that uses any of these variables in a its
regexp
# must have the '$' special before the regexp to tell
procmail to
# do variable expansion on the regexp.
# That matches if there exists a embedded Content-whatever
header field
# whose value, ignoring legal whitespace, matches the regexp
# .*name="filename"
ext = '\.(scr|vbs|shs|bat|com|exe|pif)'
:0 B
* $
^Content-(Type|Disposition)*:${dotstar}name${ws}=${ws}${dq}.*${ext}${dq}
