Backscatter solutions

[Scott Likens]

I wish that was really true,

However having a spammer recently using my domain and email address to  
spam viagra.  SPF etc don't really work unless the receiver is using  
SPF checking.

The simple truth is, bots check mailing lists, spam as users like you  
or I.  They find a new target, and start over and over again.

They don't care about SPF, or  anything related to that.  Because if  
5-10% of their spam gets filtered, that still means they were only  
shorted by 10,000 emails maybe.

... Truthfully the real solution is for ISPS to cancel those accounts  
when reported, and report them when you catch them.  It's a cat and  
mouse game that until there is a OS that 90% of the World uses that  
isn't exploitable in under 30 Seconds... will never end.

As there is always some vulnerability, there is always someone willing  
to use that vulnerability for purposes of making money.
