  Description     : Anti-Spam-Daemon using nolisting/iptables

mxallowd is a daemon for Linux Netfilter (using libipq) which implements a
slightly improved nolisting mechanism. It requires your name server to be
configured to return two MX IP addresses, and the one with higher priority
must not run a mail server on port 25. mxallowd blocks attempts to connect to
the mail server unless the sender tries to connect to the first mail server
before the second. Since most spammers will attempt direct connections to each
mail server, they will be blocked.
