Description-en: Anti-Spam-Daemon using nolisting/iptables
mxallowd is a daemon for linux/netfilter(iptables) which uses nolisting
(http://nolisting.org). That means, you define two MX-servers in your
nameserver and mxallowd will block the access to any of these mailservers if
the client did not try the other one. This blocks non-RFC-compliant mailers,
which are often in use by spammers and so-called direct-to-second-mx which is
also a technique mainly used by spammers.
