Mailfilter README.Windows 0. GENERAL INFORMATION Mailfilter is a flexible utility for UNIX (-like) operating systems to get rid of unwanted spam mails, before having to go through the trouble of downloading them into the local computer. It offers support for one or many POP3 accounts and is especially useful for dialup connections via modem, ISDN, etc. Mailfilter connects to any POP3 mail box and compares part of its content to a set of user defined filter rules. That way the spam gets deleted directly on the mail server. With Mailfilter you can define your own filters (rules) to determine which e-mails should be delivered and which are considered waste. Rules are regular expressions, so you can make use of familiar options from other mail delivery programs such as e.g. procmail. Mailfilter is released under the terms of the GNU General Public License. For more information, see the COPYING file provided with the Mailfilter program. The latest version of Mailfilter can be obtained from this web page: http://mailfilter.sourceforge.net/ 2. HOW TO COMPILE MAILFILTER ON WINDOWS 9X/2000/NT Mailfilter was originally designed to run on UNIX (-like) operating systems. With some additional libraries installed such as for example, the Cygwin environment, DJGPP or MinGW, it is possible to compile and run Mailfilter on the Windows 9x/2000/NT platforms as well. All three products can be obtained from: http://www.cygwin.com/ http://www.delorie.com/djgpp/ http://www.mingw.org/ After you have installed DJGPP or MinGW for example, you should have all the necessary tools and libraries on your hard disk to translate the Mailfilter source code. 3. FURTHER READING This document is intended to give merely a brief overview of what is necessary to make Mailfilter run on the Windows 9x/NT/2000 platforms. For more detailed instructions you should also have a look at the official Mailfilter homepage. At the moment, Bob Paddock provides the `official' Mailfilter installation guidelines for MS-Windows and also offers the the binaries for download. Find it all on his web page: http://www.csonline.net/bpaddock/mailfilter/default.htm 4. BUGS Even though we have tested Mailfilter thoroughly and particularly with Cygwin and DJGPP, we have noticed that sometimes Cygwin acts up trying to pre-compile filter rules (Regular Expressions). If you encounter such an error as well, please let us know, so we can try to resolve this issue. Thank you. There are no such bugs known when using DJGPP to compile Mailfilter. In case of trouble, you might as well use that environment. (Yet someone has to try Mailfilter on MinGW though.)
