MDspamfilter

MDSpamP is an extended spam and file type filter for the MDaemon mail
server.



As distributed, it performs content scanning of email attachments to verify
content types match file extensions. It can perform scanning of files inside zip archives.



The filter will then block all emails with not allowed files types and with
file with contents that do not match their file type.




This filter is based on the excellent MDaemon API examples and incorporates a python environment for easy updating. You can extend or modify the filter in python without needing to recompile the entire plugin.



I am releasing this to the community in case other administrators are having
the same frustrating time with their users as I am and need more power to scan incoming mail.
