pgl4rbl implements a Postfix policy server that mixes two widely used techniques: greylisting and RBL (DNS blacklists). The idea is that greylisting is applied only to SMTP clients that match a RBL; this means that normal clients are not delayed (such as with a normal greylisting implementation), and RBL false positives do not cause problems (like when outright blocking them at the SMTP level).
ExtraWatch is a real-time counter and live stats module for Joomla!, Wordpress, Drupal, Magento, and Prestashop. It allows you to view information about your visitors and bots in real-time from the administration back-end. It details IP addresses, countries of origin, geographical location, which pages they are viewing, and browser and operating system. It creates daily and all-time stats from these data plus unique, pageload, and total hits statistics. Furthermore, you can block harmful IP addresses, see blocked attempts, evaluate trend charts, and create goals based on many parameters. In the front-end, it displays top countries, and user and visit information for certain periods of time.
Using email storage in single folders makes it hard to train DSPAM. Sending email to the firstname.lastname@example.org alias works, but a more user-friendly system is needed. Additionally, since Mozilla Mail (Thunderbird) does a good job with 'Junk', it would be useful to process all user files for 'Junk' in their home directories. This small program grabs the DSPAM signatures of each email in the files provided and feeds them to DSPAM.
