Hi List We increasingly notice, that when an account got phished, it is being abused to send spam from usually one or two Amazon AWS US IP Addresses simultaneously, staying below our account auto-block thereshold.
Quite some time in the past, when I first observed this, contacted the Amazon Abuse Desk, including the infos they provide in their WHOIS entry in the past, but newer ever got any kind of reaction. Now I am curious, do others also make this observation? How about blocking the Amazon AWS IP ranges? Are there any legitimate emails being send by them? Well I could try to block them only for Authenticated SMTP submission, not for MX operation.
