Spam and Email Headers (I/II)

Hey, is spam bogging you down? Is it clogging your Inbox? Has it become a nuisance in your day to day life? Deleting them is an easy way out, but if you want to really fight spam then read on…

Wouldn’t be great if you could stop spam? To do that, it is always best to get to the root cause of a problem. In this case, spam can be stopped if you shoot a complaint to the Internet Service Provider (ISP) or the DataCentre from where this spam originated.

Staying off the Blacklist

In my last post I mentioned how setting up a Feedback loop can help you keep track of spam reports for your server. I realized that it helped tackle only a small portion of the problems faced by Webhosts when it comes to email blacklists. So in this post we’ll take a deeper look at what a Blacklist is, how you can use it and you can avoid getting your own IPs on a Blacklist.

What are email Blacklists?

As the name suggests, an email blacklist contains a list of IPs that have been reported to be a source of spam. Most blacklist authorities implement what is called a DNSBL – DNS-based Black List. This is similar to a the normal DNS, only instead of querying to get the IP address of a domain name, we query the DNSBL to see if an IP address is on that list. It returns details as to why the IP address is listed on that Blacklist, usually including a URL that can be visited to get more details.
