Topic: e-mail filtering

[Nathan Fowler]

Well to be quite honest I have mixed emotions about the deal.  It seems to be working, but not quite as well as I hoped.  I'd be more than willing to send you the binary and the source if you wanted to make changes.  We have added domain filtering as well as per acccount filtering.  I'm running into some problems with some of the SPAM I get, and I wonder if the problem is with qmail itself.  For the most part though, the logic is sound, and in the test environments I've got it working well.  I'm using it in production mode on my mail server now (this box, stickit.nu) for this account and I have very little problems.  The new C++ code can quickly parse a 35,000 list file in under a second, so it may be working out well.  The downside is the spamfilter must be configured on a per-user basis.  THe spamfilter program will look at a global file, and you can opitonally specify a user file.  Like I said, let me know if you want to take a look at it.  It's still in a development stage and I just haven't had time to dedicate to this project, I've been busy at work and I'm getting married on Feb 02, 2002 so most of my time is consumed.

Thanks,
Nathan

I wake up this thread again.

Natahan, did you ever finish this filtersoftware?

Let me (us), know.

[Nathan Fowler]

Actually, yes, and I've been using it for over a year now.  I wrote it in C++ for the speed advantages, and I'm currently using it on a production server and have been for quite some time.  A few of my buddies are using it as well.  I wrote a  PHP front-end to allow users to manage their own spamlist.

Note, it's pretty crude with respect to documentation, and I've been unable to create the energy necessary to create the documentation.  I believe the code to be stable and have had no issues for over a year.

It supports:
Wilcard domains, IE:  *.yahoo.com, *.com, *.br
Domains:  mailspammer.ihateyou.com
User Accounts:  sexyjen128@aol.com

I've also written some PHP code that will import the log file into a MYSQL database.

Thanks,
Nathan
