Exchange 2013 Anti-Spam Technologies – The Sender ID Agent

In today’s post, we’re taking a look at the third anti-spam agent in Exchange 2013’s army of protections-the Sender ID Agent. This agent is one of the best protections Exchange 2013 offers against spoofed email, which is when someone sends a message purporting to be from someone else. That’s a common way to try to get around anti-spam agents by using whitelisted sending addresses or those that are more likely to get through. It’s also a very common attribute of phishing messages, so we really want to make the most of the Sender ID Agent.

Spot Spam this Holiday Season

As we approach another holiday season we prepare to spend time with family and friends, and we prepare for another round of holiday shopping. Over the years, online shopping has served as a great way to avoid the holiday crowds at the malls, and a way to stretch shopping budgets with the deluge of money saving offers available from most online retailers. In fact, online shopping for holiday gifts has become so popular that eMarketer predicts a 15.1 percent increase in sales over last year to a tune of $61.8 billion to be spent in the months of November and December alone.

Criminals know all to well that the holiday season is ripe with victims who can be easily manipulated at the sight of an offer or promise too good to be true. So just like retailers prepare for the rush of holiday shoppers, scam artists do as well. To fight back, here are some important tips to help you better identify scams related to the holiday season.

Exchange 2013 Anti-Spam Technologies – The Recipient Filter Agent

In the past couple of articles here at ASU, I’ve been writing about the anti-spam technologies built into Exchange 2013. In today’s post, we’ll continue this look at how Exchange 2013 helps to reduce spam. Today, we will take a closer look at the Recipient Filter agent. Like the Sender Filter agent, the Recipient Filter agent also looks at the SMTP protocol. This time, it is the RCPT TO: command that the agent examines. What it finds there can help determine whether a message is legitimate or if it is spam.

Banks. They’re supposed to hold on to your money. And occasionally, make money for you, that is, when they’re not bilking you by charging you outlandish interest rates and service fees, all the while paying out rock bottom interest rates for your hard-earned savings. And they’re supposed to be secure. After all, how are they going to win peoples’ business if they’re not?

If you spend any time surfing the Internet, it’s bound to happen. You come across a story, video, or mindless rant and just can’t contain yourself. You need to share. It might be a simple as a thought-provoking article about a witty video that anthropomorphizes spam,  or a story representing an endless media feeding frenzy on the crack-smoking Mayor of Toronto,  or it might just be a cute video of a cat that hiccups and farts at the same time. Whatever the tone, purpose, humor, or sheer stupidity of it, you just need to share that sucker with everyone you know.

And that’s okay, as long as you’re not doing it in Germany.

You see, in September, the German Federal Court (Bundegerichtshof, or BGH) confirmed the ruling of a lower court that stated emails sent using the ‘send to a friend’ function found on many websites are considered spam.

    Although I can understand Joseph's decision to do that, I don't completely side with him, simply because I have been spammed before and I know it doesn't feel really good. Well, that may be his goal, but you can never correct a wrong with another wrong. I just hope he found fulfillment with what he had done.

    @Peter: It seems like I missed that story about Papa John's. Is it found in here? What actually happened? I'm very interested about spamming made by legitimate companies because I feel that's what usually happens these days. Especially in Facebook. These companies are flooding my newsfeed.

    @Ran: We can't expect anything from China, my dear. I even feel that they're using this spam excuse to gain more control not only on its people but also from business operators. They love to work that way. Everything that you see is usually just a facade.
