TLim

TLim is a powerful modification to the sendmail system that is designed to keep track of the number of transactions performed by a specific IP. The software is able to identify and sanction IPs that perform more than a specified number of transactions within a specific period of time. The default action of the software is to enter the offending IP into a null route, however, this action can be customized to suit the individual needs of the user.

The primary purpose of TLim is to discourage outbound SPAM, particularly from sources such as a dialup pool of clients. The software is also able to sanction remote hosts that attempt to send email to non-existent accounts. While this feature offers great potential to combat the spread of SPAM, it is optional due to the potential for remote abuse.

The software also offers the ability to exempt specific IPs from TLim sanctions. This feature allows users to ensure that important communications are not impacted by the actions of the software.

Overall, TLim is an essential addition to any system that uses sendmail. Its powerful tracking and sanctioning capabilities make it a highly effective tool in the fight against SPAM and other unwanted email communications. With its flexible customization options, TLim is the perfect solution for businesses of all sizes.
