Why do I get bounced mail which i never sent ?
Many spammers and viruses will automatically select random. Email addresses to send emails to (to promote their product or to infect people’s computers).
They will also randomly pick addresses to say that the email will be sent from that address (known as Email Spoofing). This is done to increase the validity (or indeed suspicion) of the desired sender’s address.
Unfortunately, spammers send e-mails and viruses using open relays (servers that do not require authentication). Frequently use your own integrated SMTP servers to send out viruses. This is because the fraudulent emails come from a different source. We don’t have a way or you to stop that.
You should get most up to date if you think you are infected with a virus. The software to check your system against viruses. To be secure (particularly for Windows with Outlook, because the e-mail program for e-mail virus authors is the most popular). And email, which is not dictionary words, or which is easy to imagine or otherwise, should always be used for your account with well-selected passwords. This prevents the compromise of your email accounts only for those purposes.
NOTE: The ideal way to stop spammers and viruses from bouncing back messages. Is to disable catch-all email in your control panel.
