# Usage:
# exim-filter-mime.py <mime-type> ...
#
# Example:
# exim-filter-mime.py audio image/jpg video
#
# This script reads from stdin and writes to stdout.
# It strips all the mime attachments from a mail message
# that are one of the mime types listed on the command line
#
# Exim can use it in its configuration file, for example, as follows:
#
# remote_smtp:
# driver = smtp
# .
# .
# .
# transport_filter = /etc/exim-filter-mime.py audio video image
#
# The attachment is replaced with the following:
def cheeky_response (part):
print "[File `%s' of type `%s' is meant to go here]" %
(part.getheader('Content-Description'), part.gettype ())
print
print "This host is restricted from transmitting %s files and" %
(part.getmaintype (),)
print "hence this attachment was stripped from the mail message."
print
import sys
import mimetools
message = mimetools.Message (sys.stdin, 0)
# Print out the header:
for l in message.headers:
sys.stdout.write (l)
print
# Not a multipart message, so just dump the whole thing:
if message.getmaintype () != "multipart":
l = " "
while l:
l = message.fp.readline ()
sys.stdout.write (l)
sys.exit (0)
# Mime boundaries:
boundary = "--" + message.getparam ("boundary") + "\n"
lastboundary = "--" + message.getparam ("boundary") + "--\n"
l = " "
while l and l != boundary and l != lastboundary:
l = message.fp.readline ()
sys.stdout.write (l)
while l and l != lastboundary:
part = mimetools.Message (message.fp, 0)
if part.getmaintype () in sys.argv[1:] or part.gettype () in
sys.argv[1:]:
# If it is of a type on the command-line, do not write the header or body,
# just skip over till the next boundary...
l = " "
while l and l != boundary and l != lastboundary:
l = part.fp.readline ()
# ... and then give a cheeky replacement:
print "Content-Type: TEXT/plain; charset=us-ascii"
print
cheeky_response (part)
# write the boundary:
sys.stdout.write (l)
else:
# if it is anything else (like text/plain, application/octet-stream etc.
# then write the header...
p = ""
for p in part.headers:
sys.stdout.write (p)
print
# ... and then write the body
l = " "

sys.stdout.write (l)
