Hello DP Members, Recently I had setup VPS and push my domain there and setup website and did rest of things, now after few days my many people complaining that they had received email from my site with attachment which content virus or something that is not downloadable. They had forwarded that to me also & I am shocked to see my website address used in email but actually in my account there is no email created like that. So some one sends random emails from and I can't stop them because I don't know how to stop. If anyone have faced this situation then please advise me how to fight with them and how can I stop this type of mail permanently because some webmails putting emails from real email address in spam/junk box so they are blacklisting my domain. The mail content are something like this And the attachment cannot be downloaded and none of email really exist on my mail server.
There is absolutely nothing you can do to stop them sending an email in your name. I could write a script in 5 minutes that could send spam to millions and make it look like you sent it. What you can do is make sure they're not using a vulnerability on your site/server to actually send from your IP research and add some of the security keys you add to your dns settings
Yes. Nothing, unfortunately. The same situation is with the spoofing of numbers for sending SMS (via the Internet). Fraudsters send sms, indicating any phone number.
