Red face Security issues!

Hi!

I have a few issues i would like to fix with my server.

1) How do I fix this:
Quote:
Some of your nameservers provide recursive lookups. This is bad since it could be used to poison caches or other DNS attacks. The following nameservers indicated that they support recursive lookups... blablabla
2) And this:
Quote:
Some of your MX servers do not have reverse DNS (PTR) entries. Some mailers will refuse to send email to your domain.
3) Is this good or bad? and what file is it?
Quote:
Your web server appears to reveal version information. This can pose a security risk if vulnerabilities are identified in this version. You should consider disabling version information in your server configuration.

Ask your provider (the company that manages your server's public IP) to create a PTR record for you.

Take a look at http://httpd.apache.org/docs/2.0/mod...erversignature and http://httpd.apache.org/docs/2.0/mod...l#servertokens
