196.171.39.7 spamattack
They took over somehow my domain. I believe they have some buggy DNS servers that allow it do such thing. While they do have my domain for a little while - they are using my company's real email address to send tons of emails to nonexistent email recipients (hotmail, yahoo, google, etc. (public mail providers)). After a little while I get back tons of NDRs in my SMTP gateways and in corresponding user mailbox. Now the tricky part - I have to be on time when NDRs come in my SMTP gateway - because I have to remove them as soon as possible or there will be another loop and I my SMTP gateway will banned to global spam lists (p.s. It is banned now)
