Outgoing spam is a major head ache for many web hosts. Spammers use compromised websites or mail accounts to send thousands of spam mail within a few mins.

1. Spam scripts uploaded to a hacked web site which has outdated and vulnerable web applications(WordPress, Joomla, Drupal, etc).
2. Stolen/leaked passwords to email accounts that allow spam mails through email authentication.
3. Un-secured email server that acts as an open email relay. (more…)

Gmail is one of the most reliable and reputable mail services. So it piqued our tech team when our billing division reported that Google seemed to think our server is a spam source.
We routinely keep track of all spam black lists, and were quite sure that the server reputation was not affected. The mails that were sent to other major providers like Yahoo, Hotmail, etc were not affected. Only Google was sending all our mails to the spam folder.

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. Nowadays, most ISP’s have a “zero tolerance” policy against spammers. As per their policy, they can delete the spammers account, make them pay hefty fine or even send them to jail! Yet, we are to blame to, a majority of this spam goes unreported. (more…)

But it was of no use at all. Finally I heard of ASSP. This is my lifesaver. Now all my clients are happy and content. The spams mails have been reduced by more than 90%. None of my clients have ever mentioned about spam, ever since this software was installed. Let me tell you more about my experience with ASSP
