Blog - Bounced spam attack on the up
Bounced spam attack on the up
Since a while I've always been getting batches of bounced spam every now and then. Lately it had been stable at a few hundreds per day, which I've come to call "normal". But yesterday I got 2000 emails! I'd check email after just a few seconds and there'd be a dozen.
I had to do something a bit more drastic to stop this mess, so I looked at what most of these emails had in common. This time I targeted the "To" field, which has most of the time been using very long aliases, and I used CPanel's mail filtering to blackhole anything too long.
Filter: $header_to: matches "[a-zA-Z0-9]{17,}@"
Destination: Discard
So I'm now back to a peaceful, low level of spam (by my standards).

Spam - how I hate that!
They now started to fill in even the contact forms on our webs which must be manual work (at least once to find and identify the field name).
If the Internet would be a music CD you could not hear the music without heavy filter equipment. 1% music but 99% distortion. In the Internet it is normal to filter the few interesting drops of information out of an ocean of junk.
Btw: Patrick - keep up your good work - chipple.net and tokyorecohan.com are one of these few drops worth the trouble!
