Question

I am looking for a .NET/ JAVA free or opensource SPAM detectors accesible via an API that yield good results. I would consider paying for a good service that accomplishes this as well, but ideally, I would like to go open source. Does any one have any good experiences with any or recommendations?

Ideally, I would get the text/markup to a message in memory, I would call a method from this API, and it would return a bool or likelyhood of SPAM.

A quick google search yielded some results, but users with experience to share are greatly appreciated.

Checkout the Akismet .NET 2.0 Api on CodePlex.

Here s an example from the CodePlex page:

// Verify key
Akismet api = new Akismet("key", "http://url.com", "Test/1.0");
if (!api.VerifyKey()) throw new Exception("Key could not be verified.");

// Create comment object for testing
AkismetComment comment = new AkismetComment();
comment.Blog = "http://joel.net";
comment.UserIp = "147.202.45.202";
comment.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)";
comment.CommentContent = "<a href="http://someone.finderinn.com">find someone</a>";
comment.CommentType = "comment";
comment.CommentAuthor = "someone";
comment.CommentAuthorEmail = "backthismailtojerry@fastmail.fm";
comment.CommentAuthorUrl = "http://someone.finderrin.com";

// Test comment against akismet s service
bool isSpam = api.COmmentCheck(comment);

Akismet rocks.

One easy way to implement this is to setup a Google domain account for your email and let Google deal with your spam. Then you can either access that account using regular pop3 or imap api or simply forward all email to your real account.
