Hi everyone. I'm sending this email because I'm looking for a reference regarding smtp attacks, this is because I'm working to create some smtp signatures for the snort solution.
It's not directly with snort, I'm willing to contribute with the bleeding snort proyect. I can't find any information regarding the smtp attacks only the relay test and that kind of stuff. The question is: Is there any book related with smtp attacks, exploits or any other type of attack related with the smtp protocol? I will highly appreciated any recomendation, this signatures will help us everyone. Thanks in advance. Alfonso.
