Can a hosting service stop someone spamming from my domain?
Discussion
I've just started receiving spam from my own domain. I assume someone is spoofing the addresses, as they aren't real.
If someone is spoofing my domain, do the emails travel through my hosting provider, and can they do anything about it? There are only 2 real email addresses in the domain!
I'm still with 1&1 for my sins!

Your hosting provider might be able to stop this but it really depends on the flexibility of their email system, and whether it's worth the time to implement the change, or whether they can implement it just for you.
It should be possible to perform a check so that only authenticated local users (eg people who have an account) are allowed to send using a local domain name.
This means if an email comes in from an un-authenticated IP address, and uses your domain as the sender, it's rejected. This will be extremely effective at stopping spam sent direct to you using your domain as the sender, but useless at stopping bounces, failed mails, or any other type of spam.
The easier solution is to find some effective anti-spam software and use that, as it should stop most of the spam regardless of sender.

Ah ok, in that case - they can stop it coming into your account but as ThePassenger says above they can't stop this spammer from sending to other people using your address.
There do exist technologies such as SPF which would all but eradicate this, but it requires everyone to have perfectly configured DNS records and understand the technology, and precious few DNS or mail server admins do.
This means the tech can't be implemented because doing so will likely block most incoming email!
