Some one is now sending emails out through [email protected]???

[splitybus]

Not very sure about the security side of things but someone is now sending emails via [email protected] to everyone that has registered with my prestashop site?

whats the best way to combat this and secure my shop and also how can someone use my email addresses?

Anyone can send an email that will show up from [email protected], if you look at the header of the message (which very few people do), you will be able to see which actual domain in was sent from (and know if it's a fake or a real email).

If someone is sending emails to all the registered users on your site, you have most likely been hacked.
Did you use a good password?
Did you give it out to anyone?
Has your computer been hacked into?

The best thing would be to change the admin password and rename the admin directory.

Good luck.
