I’m Not the Only One Apparently – Gmail’s Growing Spam Problem

A while back I wrote this post pertaining to what appeared to be spammers utilizing Gmail servers to send spam to my account. I didn’t know if it was just me or if others were experiencing it as well. It’s not just me apparently. This article on The Register in the UK shows that this is quite a growing problem for all mailing systems, that is now causing many mail services to start throttling Gmail (as well as Yahoo) emails that come in. This is bad news because Gmail was supposed to be one of the more secure mailing systems. In addition, it presents a big problem for services like Spamhaus because spam emails being sent through Gmail SMTP servers are not blacklisted. Therefore a spammer can send email from foreign IP address blocks that may be banned in the Spamhaus database, but because the email is actually being sent via Gmail servers, it is not blacklisted. So mail services have started enforcing throttling to limit the number of email that are sent from Gmail. This just shows that no matter how much security you put in place (even complex CAPTCHA techniques), there is always a way around systems, always. And at some point, someone will find the holes. It’s just a matter of time. The trick is staying ahead and always keeping people guessing.
