I've got mail is a witty take on spam from Richter Scales. It is a 2007 CARA Nominee in Best Humor Song category. Listen to find how spam gives meaning in life, not to mention three additional inches and more.

Ever since we installed Comment Guard Pro, anti comment-spam plugin on this blog, it stopped over 1 millon spam comments (1001011 spam comments were blocked by Angsuman's Comment Guard plugin in 335 days 8 hours 38 minutes. 99.338 % of the comments received during this time were spam.) so far (look in the right sidebar for latest stats). The pro version of the plugin is now being tested on this blog and other sites.

In Comment Guard Pro have developed multiple layers of defense to stop all kind of comment spams - spams submitted using comment forms (robotic or by humans), pingback spam, trackback spam and referrer spam.

Comment Guard Pro is a modular plugin where each module acts as independent spam filters. Many modules are developed with technologies developed in-house. Others leverage best existing technologies out there. You can also develop and add your own modules as well as share it with others.

So far it is all-green on QA front, only minor defects and enhancements.

UPDATE: Comment Guard Pro has been released.

I used to receive around 5,000-7,000 spams daily on angsuman [at] taragana [dot] com email which is publicly available on the internet. It was consuming too many productive hours daily to fight spam. I decided to fight back. To reduce the spams I first made changes to my postfix configuration with the aim to stop most spams upfront. With 6 simple changes to my postfix configuration my spams dropped from 5,000 - 7,000 to a manageable 5-20 spams daily, often less. Let's look at these 6 simple postfix changes in details to drastically reduce your spam count too. I am consistently getting over 99% spam reduction after implementing these changes.

The changes proved to be safe and without false positives. In several weeks of manual browsing through the log file, I couldn't spot a single false positive (a case where legitimate mail is rejected).

Note: This changes do not involve (nor do they conflict with) spamassasin or clamav, which I might add later.

I finally grew tired of email spams, having to delete several thousand spams a day while fishing out for valid emails is no fun. Occasionally I deleted valid emails too in the process. I realized I was wasting valuable productive hours dealing with junk from cretins and morons (aka spammers). I decided to fight back.

We are tweaking our postfix servers to offer maximum spam protection upfront with helo checks, header checks, blacklist checks, RBL's and more. So far my daily spam count has dropped from about 3000-7000 spams / day to about 15-35 spams per day. It should drop even more as I added more RBL to my list (see below for updates).

Sometimes you need to view the full email headers to understand whether an email sender information or other details is faked or to even debug your MTA (my situation). Unlike other email clients GMail doesn't give you an intuitive way to get the full headers. Nevertheless when you know it, it is very simple. Here are the steps:
