DynaStop is a utility to examine IPv4 based addresses for Exim and procmail for the purpose of filtering based upon patterns defined by the administrator. This can be a pivotal factor in email filtering and server load management, since dynamic IP addresses are typically used for dial-up, DHCP, and DSL accounts. All of which have a designated mail exchange server through which all outbound mail flows as defined with many, if not most, large Internet service providers.
dyn-host-filter is a stand-alone application used to restrict the access to qmail based on the client's hostname/IP. Each incoming entry is compared to a user-defined list of regular expressions. dyn-host-filter may reject a matching entry by modifying the RBLSMTPD env. variable used by tcpserver.
DynamicRelay prevents your customers from sending spam, and authenticates users using POP or IMAP to send email in a pop-before-smtp fashion. You can use it with the wu-imap, dovecot, Courier, and Qpopper IMAP/POP servers, and with Postfix or Sendmail. You set the limit to the number of email messages a user can send per day. This is useful when you have users infected by viruses that send thousands and thousands of spam messages, or who send spam deliberately. You can also control how long users are allowed to send email after their last POP or IMAP authentication. Abuses are logged and emailed to you, and you can put your own static entries in the access file.
EScrambler - Email Address HTML Code Scrambler, is an email address code scrambler. It makes your email addresses invisible to SPAM crawlers. Visitors to your web pages can read and click on your email addresses the same way they do now, but robots will not find them. Search engine friendly, and easy to use.
EmPy is a system for embedding Python expressions and statements in template text. It takes an EmPy source file, processes it, and produces output. This is accomplished via expansions, which are special signals to the EmPy system and are set off by a special prefix (by default the at sign, '@'). It can expand arbitrary Python expressions and statements in this way, as well as a variety of special forms. Textual data not explicitly delimited in this way is sent unaffected to the output, allowing Python to be used in effect as a markup language. Also supported are callbacks via hooks, recording and playback via diversions, and dynamic, chainable filters. The system is highly configurable via command line options and embedded commands.
