I think you have seen the msgs about procmail filtering today. Well, I
just played with exim system filter option and came out with a initial
filter that can extended to match your needs.
the filter is (please exim gurus improve it; it's my first step in this
area):
-----------------------------------------------
# Exim filter
if $header_Content-type matches "(multipart/mixed|application/octet-stream)"
then
# if $header_Content-Disposition matches "(attachment|inline)"
# then
if $message_body matches ".*ame(=|:).*\".*\.(vbs|wsf|exe)\""
then
deliver [EMAIL PROTECTED]
endif
# endif
endif
-------------------------------
the file must start with # Exim filter
this is not a my comment; it's a exim requirement.
also note that I tried to incorporate the Content-Disposition header but
I think it's not always present.
also note that I wouldn't able to change the names of the files; instead
I deliver the messages to postmaster for checking and then, it's safe,
to the original user (they're preserved in the headers).
