Forged Email Headers

What do you do if some spamming dickhead decides to forge their headers to make it look like all the crap they’re sending is coming from your domain?

I’ve already put a help ticket in with my hosting provider reporting the problem, and I’m archiving all the bounceback messages. I’m not sure what else there is to do. I don’t really have the time right now to sift through all these messages trying to track the culprit(s) down.

  1. Just got an email reply from tech support


    What is happening is that someone is spoofing you domain to an “Open
    Relay” email server. This is a mail server that is not one of DreamHosts,
    and it allows people to send email through this server with any domain
    that they want to use. There is nothing that can be done about this
    unless you can find out what mail server they are sending it through. Let
    me know if there is anything else I can help you out with.

    Gee, you think? Okay so I didn’t use the phrase “Open Relay” in my email to them, but I’d figured as much out on my own.

    Sorry, not really mad at DH or the tech support guy that replied to my message. I’m just frustrated with the situation, and the reply feels a bit like a paroting back of the message I sent them earlier this afternoon.

  2. Eh, you could try to fight them, you could possibly figure out what relay they’re using and try to contact that host and ask them to tighten up a bit. I know they could just move on to another relay somewhere else, but eventually… if everyone actually did something about it, they’d run out of places to use as an open relay (ah to dream)
