Kens Spam Filter 1.40

Free Spam Filter - Stop Spam - Free Spam Blocker

Also very effective at blocking email based trojan and virus.

Recently like many of us, I have been getting a huge amount of spam (junk emails) I have tried several of the anti spam programs that are around, but none of them really suited me.

Some cost money, and that really did not suite me, others needed far too much user intervention, and none of the ones I tried were 100 percent effective, leaving me to spend at least 15 minutes a day deleting the spam messages that got through.

What I really wanted was an anti spam program that was 100 percent effective, that ran in the background, and needed no intervention from me, such as the daily manual selection and deletion of spam messages that get through, and of course one that did not need an annual fee to keep it running.

I could not find such a program, so the only solution left was to write one, and here it is.

It is not an easy program to install, mainly because I have not got around to automating the install process, so if you want an easy ride this software is not for you, but if you are prepared for a little work, and follow the step by step instructions in the help files you will end up with no spam at all, and what's more you won't have a thing to do, just let the software get on with it's job.

How does it work?

Kens Spam Filter sits in between your normal mail program and the outside world, everything you send passes out through the filter, and everything you receive also passes through it.

It has two lists, a list of email addresses from whom it will accept mail, and a list of email addresses that it will reject mail from.

When a message arrives from an unknown user the message is held and a reply generated and sent back to the sender asking them to reply back with a subject line that contains a keyword, this keyword is the letters KSF followed by a short serial number.

If they reply back, all future messages from that person will pass through the filter, and all presently held messages from that email address will be released.

If they don't reply any future messages from them will be ignored, most spammers don't even use real addresses, so they won't ever see the registration request.

On the sending side things work in a similar way, anyone you write to is automatically added to the friends list, so when they reply to you they will not be asked to register as they have already been registered by the simple act of you writing to them.

You can of course manage the allow and blocked mail lists manually, but why bother, unless of course a spammer manages to send you a password, if that happens simply add them to the blocked list and forget about them.

KSF is written in C# .NET and will make use of the ,NET framework, you can get it from the windows update site, or you can download it from this link.

Kens Simple Server
As an alternative to the above Spam filter I have now written this one, it is much more basic, but equally effective This one works by building up a database of people you write to, then only passes mail through the filter if it is from someone you have previusly written to.

 

Therefore it is invisible in operation, you write to someone, and they can also write to you, it's that easy, mail from anyone else will be marked as possible spam.

 

This program has another built in hidden feature, it can be used to stop your employees from using the companies computer for private emails, you set it up slightly differently, and from then on only emails will pass through the system if they are to a list of people or domains you mark as allowed, all other emails will be blocked, effectively stopping users from writing personal emails in company time.

 

This server can be made to run as a hidden service so it will run virtually undetected, and full source code is included, download it here.
