EmSniff is an application that helps you to capture network packets. It differs from TCPDump in that it runs as a service instead of an application. This makes it possible to capture packets in the background. This can help applications like Wireshark to be more secure since they don't have to run with root privileges anymore. They only have to connect to the EmSniff server via libemsniff.
SpamAssassin Flagging Milter is a Sendmail milter daemon for Unix systems. It sends email to Spamassassin and then modifies the headers based on the results provided by Spamassassin. It adds a Spam or NonSpam entry in the headers, which client programs can then use to help filter junk. This program is based on another program, milter-spamd: http://www.benzedrine.cx/milter-spamd.html.
