look out for a ready-to-use script named "sanitizer" which might be
exactely what you are looking for. (dont know the url, but should be easy to
find)

I need to be able to block unsafe attachments in e-mails that come in. I
have looked through the archives and found this from february. it doesn't
seem to work when I paste it in. I'd rather it go into a junk mailbox that I
have setup to trap spam, not to /dev/null, but that SHOULD be an easy fix.
Thanks for your help, I'm something of a neophyte with this stuff.

I'd like to setup procmail to block file attachments with certain
extensions like .vbs, .shs, etc. How would I do this. I've checked out
here's a recipe, all credits go to Philip Guenther, I've just added
extensions I need to filter to his regexp.
# The regexp for matching whitespace in the embedded header field
# of a multipart message. We have to handle wrapped lines.
ws = '[ ]*($[ ]+)*'
# The regexp for matching 'anything' inside an embedded header
# field of a multipart message. That is, it matches anything
# except the newline (not followed by a whitespace character)
# that terminates the header field.
dotstar = '.*($[ ].*)*'
# 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}
/dev/null
