This is because SMTP does not offer great spoofing protection, so typically you can connect to a server and claim to be someone else. The best way to fix this would be to set up an SPF record with a hard fail, which is expressed using a- and typically is at the end of the record as -all. You would have to be certain of where your emails are coming from. You ...

The answer to the first part of your question is the current Gmail spam filters would not be as effective, they could read the header information and block certain sender addresses but they could not read the actual message. Your assumption that all the encrypted spam message bodies would be identical is incorrect, every individuals public key would produce ...

Everyone is trying to explain the arms race, which is true, but there is the very simple logic that if spamfilters were perfect, then spam would not exist anymore because it's no longer profitable. And a spambox would not exist because we are 100% sure of what is spam and what is not, so it could go straight to trash without landing in a spambox first. ...

OH MAN am I glad that I no longer have to deal with these. I would explain how a spam filter actually works. Generally spam filters have a "rating" system (The one provided to our company by Google worked this way). The rating would go up if it matched known-patterns The rating would go up if it matched known keywords (Many keywords related to drugs, ...

The email spam filters are not 100% effective, that's a fact and you said it correctly. As their name suggests they are filters, if something doesn't match the filter, it slips through, but that is why there are multiple levels of security used while receiving an email. Therefore if one fails, there are more checks being performed. This time it got caught by ...

A spam filter can be created that will block all spam; one could simply have the filter block all incoming email. Most users would find such a filter unacceptable, though, so the challenge is to find a balance between blocking email that users don't want to receive, but at the same time allowing through all the email they want to receive. If the filter is ...

The explanation I have always used is the analogy of "Why did my bullet proof vest not stop that bullet?" is because the bullet proof is a misnomer, and someone simply used a bullet designed to defeat your bullet resistant vest ;) Most people seem to get that concept that it is a balance of too tight (false positives restricting mail flow) and too loose ...

The main function of a SPAM filter is to block anything that looks like a SPAM. The objective of an anti-virus software is to detect and remove anything that possess the signature of a virus (worms included) based on the virus definition installed. Both programs work differently based on different heuristics. An email that doesn't look like a SPAM may ...

I like to use the analogy of an arms race as it's a familiar theme that non-technical people understand. Analogies are useful when trying to explain concepts such as this. Also throw in statistics. Last, use some pseudo-personal stuff to make them feel like you're in the same boat. Something like this may work: I completely understand your frustration with ...

You were right in your explanation. In trying to relay the issue, I would try to explain in less technical terms. Non-tech people don't like, and will have problems understanding technical explanations. So try to avoid them. Especially when they're already upset. I like to use cars. In this case, spam filters are like looking at a car. A look at the car ...

Your answer is pretty OK, but you could explain the ongoing "game" between spammers and spamfilters a bit more. This makes it understandable why some spam always will find its way to the customer. Spam filters try to catch all mail that is spam. Spammers try to create mails that are trusted not to be spam - both by spam filters and by humans. For ...

I think your answer is correct. Nothing is 100% bullet proof. That is why the user has to have some awareness and some knowledge to understand when and how things look strange and what to do next. (this last part is forgotten and people tend to trust too much in applications) That is why those situations occur, people discover that applications are not 100% ...
