You must be either hosting couple of user accounts only or you had never spent a second reading your servers' logs. Exampke below, just randomly-picked machine I have, todays log (and I see thousands of this shit daily; replaced target, legitimate domain with @x, but it does not really matter): Nov 14 08:48:01 from: [email protected] to: carverwwymtjwb...@x origin_ip: 87.238.155.82 origin_rdns: (unknown) auth: (unknown) Nov 14 08:48:01 from: [email protected] to: cichoc...@x origin_ip: 87.238.155.82 origin_rdns: (unknown) auth: (unknown) Nov 14 08:48:01 from: [email protected] to: s...@x origin_ip: 87.238.155.82 origin_rdns: (unknown) auth: (unknown) Nov 14 08:48:01 from: [email protected] to: account...@x origin_ip: 87.238.155.82 origin_rdns: (unknown) auth: (unknown) Nov 14 08:48:01 from: [email protected] to: g...@x origin_ip: 87.238.155.82 origin_rdns: (unknown) auth: (unknown) Nov 14 08:48:09 from: [email protected] to: cichock...@x origin_ip: 87.238.155.82 origin_rdns: (unknown) auth: (unknown) Nov 14 08:48:09 from: [email protected] to: b6da4...@x origin_ip: 87.238.155.82 origin_rdns: (unknown) auth: (unknown) Nov 14 08:48:10 from: [email protected] to: df68a...@x origin_ip: 87.238.155.82 origin_rdns: (unknown) auth: (unknown) Nov 14 08:48:10 from: [email protected] to: j...@x origin_ip: 87.238.155.82 origin_rdns: (unknown) auth: (unknown) Nov 14 08:48:10 from: [email protected] to: rc...@x origin_ip: 87.238.155.82 origin_rdns: (unknown) auth: (unknown) Thanks to graylisting they are kicked away at doors. Now apply your graylisting to the above logs and see how it "works" :) Regards, -- "Daddy, what "Formatting drive C:" means?"...
