Not sure if this is the right forum.....
Also not sure what I am talking about....
I keep getting emails returned as undeliverable that I have not sent ( often containing DELETEDO.TXT ) so someone is obviously accessiing my email system. ( my own system provided with my domain by my webhost !&!.co.uk )
There is no evidence that I can find of them coming off of my own computer ( protected by Mcafee antivirus and firewal ) so I think they must be accessing my host server direct.
What the xxxx do I do ?
