    blacklisting [email protected], does it work to stop spammers?

    now, i checked and rechecked, and the address "[email protected]" 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 protected]" or "[email protected]"?

    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:

    Code:
    • Blizzard US DNS: ob3.blizzard.com IP: 216.148.0.68 Blizzard EU DNS: eu-smtp02.blizzard.com IP: 80.239.172.105 Or DNS: eu-smtp01.blizzard.com IP: 80.239.174.216 Blizzard insider DNS: info.cme.vugames.net IP: 12.129.240.41 Or DNS: email.blizzard.com IP: 12.129.200.219
    these are the mail servers that are officially used by blizzard, i doubt anyone can send a mail like it comes from these servers.
    Because I want to say this every single day but don't want it to get a drag:
    1) The ingame store will only sell timesaver items. It won't affect balance.
    2) No, getting to 100 in half the time isn't pay2win. raids don't start until the second week, everyone has time to get there.
    4) getting charms faster is also not pay2win. getting those is easy, but not everyone has the time or want for dailies.

    In theory, it would work. In practice, nearly any part of the email header can be spoofed. Also in practice, not many spammers bother spoofing anything but the From Address.

    but what about my second part: is it possible to block all mails from a certain domain that aren't from one of those 5 IP addresses?

    That totally depends upon your email system.

    All of those are legit blizzard emails. Yes, I've been hacked before. I put dates to show that they have been used recently, the october third was a friendly reminder to let me know blizzard wanted more money from me

    edit: all of the 'noreply' are from '[email protected]'
