A lot of spam is sent by zombie PCs that have been hijacked by a virus or trojan. The owners have no idea their machines are infected. As many of you are aware, you can install firewalls and virus scanners to reduce your risk of this. However, many people don't do this. They're not tech savvy enough to keep their PCs safe.
I was thinking there needs to be a very simple solution that doesn't require PC configuration. Something that Grandma would have no problem using. I was wondering if there's a way the router could let you know when mail was being sent.
If the router were to beep every time it made an outbound connection to the mail port 25, the owner would be able to hear when unauthorized mail is being sent. If I heard a beep after I sent mail, I know that's from me and it's safe. But if the thing is beeping constantly 24 hours a day, I know I have an infected machine. Even Grandma is going to get tired of the beeping and call someone to take care of it.
This isn't really something for spamgourmet, but I was wondering what you guys thought of this idea.
