I am receiving emails to my website email. I seriously doubt that the person sending the emails are sending them for genuine interest. It sounds to me that it is a hacker trying to get some information about me or my ip address or something as such for hacking person.

my question is: what could a hacker achieve by sending me an email with no attachments assuming I do reply to his email? How could I make sure I am 100% safe from any site hacking attempts?

What's in those emails? Any links? – amiregelz Oct 30 '13 at 12:44
This is much too broad and opinion-based, sorry. Also, it's not about computer software. How to harden your website / server is explained in the respective documentation for your scripts (if you're using third party scripts) and web server. – slhck Oct 30 '13 at 12:45
Your ip address of your email server is already known. There is no information that is contained in an email header that could directly lead to a compromise unless your server is already vulerable to an attack which as I said the ip address of said server is already known. – Ramhound Oct 30 '13 at 12:52
thank you guys. slhck, I am using my own custom code. What I wanted to know is, does a hacker benefit from knowing my personal IP address, maybe to hijack some admin login session. – siteadmin Oct 30 '13 at 14:23

If you reply then you have admitted that you exist.

He probably didn't know that before. Stand by for the receipt of huge amounts of spam from everyone to whom he can sell your address.

So? If they don't receive a non-delivery notification, assuming they send from a genuine email address (which is how it sounds in the question), they know the same. The protocol requires that the MTA send a non-delivery notification which is the reason for some forms of spam (namely backscatter spam). – 0xC0000022L Oct 30 '13 at 12:40
if it is only about spam, then I do not feel a big threat there. Anything else should i be worried about? – siteadmin Oct 30 '13 at 12:43
@0xC0000022L - In many cases this is not so. Most email servers now don't send non-delivery notifications for this very reason. – Chenmunka Oct 30 '13 at 13:15
