Is Postini (filtering e-mail spam) active anymore?
Postini was purchased by Google back in 2007, but does the entity still use their own domain “postini.com” to set traps for their blackhole? According to Wikipedia, “Postini was an e-mail, web security, and archiving service owned by Google since 2007. It provided cloud computing services for filtering e-mail spam and malware (before it was delivered to a client’s mail server), offered optional e-mail archiving, and protected client networks from web-borne malware.” Recently we had a client who needed a spam trap clean. They thought it was a gmail trap because their deliverability rate dropped over night while sending to gmail’s servers. It destroyed a lot of their business and the race was on for finding the culprit. Since Google purchased Postini, it seemed like a good place to look perhaps to find possible culprits. It’s impossible to remove gmail.com spam traps because if you remove one with the same IP, you will remove all of the gmail addresses. A lot of business’ now use gmail as their mail exchange so we dove into all business related domains to gmail’s IP’s from the client’s subscriber base.
