SpamCheetah as it stands today

Overall just by using these two algorithms spam is gotten rid of. However there are problems like initial mail delays and mail senders retrying from different IP addresses which is a problem for greylisting spam implementations. But such real life implementations are not very typical in US unless it is a big ISP.

- While I definitely have some complaints, this is fast. It's too bad it won't work on so many low end systems. -

SpamCheetah as it stands today  
- SpamCheetah is a greylisting spam control technique and it is more of a spam blocker rather than a spam filter since it really does not filter anything. -

Don't be over confident about viruses  
- Some software seeks permission it really doesn't need; again that's probably inoccuous but how would you know? The author of that installer could be up to no good, and once you type the password, it is all out of your control. At that point, you may as well be running Windows, because you have no more protection. -

Mac Viruses  
- I get really tired of hearing the old 'If Macs were as popular as PC's, they'd have just as many viruses'. That's completely wrong. Popularity might bring more viruses (as Mac viruses are effectively at zero right now, that's a pretty safe bet), but it would never reach PC proportions. -

How spammers use link farms  
- I think that, like viruses, this will be an on-going war. The search engines will improve their ability to detect artificial linking, but the spammers will find new ways to cloak it. This dance won't end all that easily. -

Dumb comment spam  
- It was hand done, and they pasted the same bragging and link on several of my pages. I use anti-spam software that kicks in if you make too many comments in too little time, so they got blocked after four posts, but that wasn't what was stupid. -

Viruses and Unix  
- I was in a meeting last week where a customer was exploring switching from a Unix platform to Windows. Of course one thing mentioned in favor of the Unix platform was the lessened threat from viruses, but someone brought up the old 'popularity' argument: if Unix were as popular as Windows, it would have just as many virus problems. -

Virus Research and Defense  
- This book by Symantec's chief researcher should scare you, because the bad guys are winning the virus wars. This book can be heavy geek territory.

But if you are the type who likes to take things apart to see how they work, this is for you. -

Roaming wireless access, spam
