Has my server been hacked?

[Matt Graham]

Hi.  I got this email (below) from someone saying that my server is
attacking theirs.  They used my IP in the subject line as well.

Is this what happens when a system is rooted?  If I suspect that this has
happened, is my best option to reinstall?

Matt

Hello,     I am not sure if you are aware that your server is conducting a
vulnerability search and is continually hitting my server.  I am guessing
that you are unaware of it since the attacking IP is riddled with personal
pictures of your self and your sister.     Could you please look into this
ASAP.     Grant.
