Spammers use our emailaddress as the reply-to, any tips? - GoFuckYourself.com

Pretty fucked up. Thousands of daily undeliverable emails come into my account as they use our email as the return address. My cellphone datalimit goes fast this way.

I doubt there's a lot one can do about it, yet I'm giving it a try.

Is there any way to see where the email is being sent from?

There's nothing you can do.

Set up a server side rule on your mail server to trash the bounces so it is killed before your phone even tries to download it.

Thanks Damian, Webair is on that as we speak;-)

There are a few things you can do with limited effect though.

DKFilter
DomainKeys
SPF

Can you explain how any of those things would help in this particular case? I'd love to learn!

Basically, you can add the ip of your outgoing mail servers as a special record to the dns for your domain. That way, mail servers (that use SPF, domainkeys etc) can detect if someone else is pretending to be you and they won't accept (or bounce) those emails.

Oh right, obvious really.

I had the same problem as the OP a year or so ago, and couldn't think of a way round it. That makes sense. Thanks.

and you couldn't make the spam disappear with a simple magic trick?

If the solutions work or not depends on the rest of the internet, but in my book it never hurts to set everything up.

With SPF you add records to the DNS of your domain listing the server ips which are allowed to send emails for this domain. If the receiver has SPF setup his mail server will check the envelope-from domain and retrieves the list of authorized server ips from the DNS. If they match the email goes through, if not it depends on their config on what happens with the email (usually rejected)

An addition to SPF is Sender ID

The concept with DomainKeys is that the sender signs the message with a key, the receiving mail server fetches the public key from the DNS of that domain and verifies the message.

SPF is widely used, DKIM not so much
