As they are "replies" to messages that we have not sent, and from people we have never heard of. It suggests that our e mail address is being used by a third party to send spam, viruses etc.
How can a mail address be used to send mail without the "owners" knowledge?
Does it suggest malware of some kind on our system or ISP's server.?
I have run several virus scans but can find nothing suspicous on our system.
This has gone on for a couple of weeks, had hoped it would have stopped by now.
Can anything be done further.?
