I'm getting more than 10000 spams sent at fake adresses every day ( looks like they are pseudo-randomly generated ) One inlog file is more than 4 Mo per day, when it was 200/300k a month ago. I had to hack a small program to tell the hit-parade of the source ip or class C ( since visual analysis is not possible any more), but there is a large dispersion of theses sources. For example, for today at 7pm I get this : logs : 8337 Err 550 from 195.188.213.0/32 : 200 Err 550 from 194.25.134.0/32 : 196 Err 550 from 195.228.242.0/32: 179 etc
I'm wondering if this is a kind of virus, or 'brute force spam' trying to reach a real adress once every 1000 tries, or both ? Strangely all fake adresses have similar patterns, such as name_<two random letters>@domain For example : [EMAIL PROTECTED] [EMAIL PROTECTED] etc do you suffer the same problem, with a recent acceleration these last 20 days ?
