I said NO receipts!
21 Jan | 06Well I still don't know why the noreceipts option in the privacy flags isn't work. But, the computer that is acting as my spamtrap is only a spamtrap so it should never ever send any mail out. As a quick and dirty hack I defined a Smart Host with a mailer of local:nobody . It works, but I'd like noreceipts to work since I don't want my real mail servers sending receipts to spammers. I turned off automatic image display in my mail program to keep the spammers from knowing they...

Darn spammers are tracking who receives mail
21 Jan | 06After doing a lot of cleanup trying to clear out clogged queues full of spam, I discovered today that spammers are taking advantage of DSNs (see How to get notified ). I had disabled the spamtrap temporarily on most of my servers, and suddenly noticed there was outgoing mail from the spamtrap, which seemed odd. Taking a look at what was in the queue, I found this (email address hidden): ----- The following addresses had successful delivery notifications ----- s...@s... (relayed to...

Are you a spammer and don't know it?
16 Jan | 06I setup my spammer logging to lookup the owner of the IP address that the spam is coming from. You'd be surprised at where some of it is coming from. There's the obvious expected places like China and DSL/cable users. But there's been some coming from government controlled IPs. My guess is there's a lot of people that are running hacked computers and the spammers are using them as relays. These people probably have no clue that they are acting as spammers themselves. So for fun...

Does openMosix really work?
16 Jan | 06Well after trying to use it for a few days in a real world application, it's failing miserably. Processes are no longer migrating, and when I have more nodes available than just the master node, things come to a CRAWL on the master node. That's crazy! I looked at all the /proc/pid/cantmove entries and they were all empty which from what I understand means there's no reason they can't move. I found out there was a problem because my disk ran out of space! Instead of processing...

Spam filtering - cluster style
13 Jan | 06Spam load again got to be too much for the computer I had dedicated to the task. Decided I really needed to give the clustering thing another try. I decided the easiest thing to do would be to build yet another dedicated computer to handle just the spam filtering. Since I would be starting from scratch on an install, I had the ClusterKnoppix CD install itself to the HD. I then burned another CD and setup 2 more computers on my cart and booted them from the CD. All 3 computers joined together...
