now, i checked and rechecked, and the address "firstname.lastname@example.org" isn't one used by Blizzard (i believe they use one of these: http://eu.blizzard.com/en-gb/company/about/contact.html). so can i safely block any emails coming from "email@example.com" or "firstname.lastname@example.org"?
maybe something even more advanced: I want to block all emails that end in @blizzard.com, but don't come from any of the following mail servers:
these are the mail servers that are officially used by blizzard, i doubt anyone can send a mail like it comes from these servers.Code:
- Blizzard US DNS: ob3.blizzard.com IP: 188.8.131.52 Blizzard EU DNS: eu-smtp02.blizzard.com IP: 184.108.40.206 Or DNS: eu-smtp01.blizzard.com IP: 220.127.116.11 Blizzard insider DNS: info.cme.vugames.net IP: 18.104.22.168 Or DNS: email.blizzard.com IP: 22.214.171.124
