we need a windows service which will check every 2 hours a spam logfile. the logfile does show per email messages a check against dns black lists. the service should scan the log and extract ip addresses on dns blacklist entries which appear 3 times on different dns blacklists. if a ip is found in 3 different dns blacklists, the ip is extracted and written to an text file.
the second tool we need is a simple command exe, which will merge the extracted ips in the text file to a binary file called smtp32.acc. the binary file is simple and explained on [url removed, login to view] website for the mailserver imail. you can download the log file sample, the acc file. the structure of the file is explained on [url removed, login to view] under IMAIL knowledge base. just search for [url removed, login to view] and you will get the structure explained. the acc file is located in imail directory and loaded eachtime the smtp service of imail is started. all ips listed in the acc file are blocked for smtp transfer, so the spammer is blocked. the windows service should run on a windows 2000 and win 2003 server machine, should be very stable and not consume much memory space.
we have added the smtpd32.acc binary file new as ZIP file, as some of the programmers asked for another format. you will also find an example txt file, how the ip addresses have to be importet to this binary file. please also find the link to the format of the acc file http://support.ipswitch.com/kb/IM-20040413-DM01.htm
this is the example format of the iplist we import into the smtpd32.acc file. we import one single ip or an ip range. for the project, we first realise the tool to import the txt file into the binary file. then the analysis service for the spam logfile will be realized.
