Please help, Some China's people try to hack my server

Is that mean for safety I need to install another firewall in my Directadmin?

Yes ofcourse, that's why I wrote:

So that's why people always should have a firewall on their server too.

For safety you should install CSF/LFD firewall which is quite easy to do and has a Directadmin plugin.

Or you can use APF/BFD firewall, which is also good but has a bit less options.

Chirpy has gone to the trouble to make this great firewall work as a DA plugin so I definitely agree that DA admins should take advantage of it. One can set it up to keep itself upgraded, which is also nice.

Ok, I will install it later, thanks

but do you know about my email's problem, how to fix it?

About the email, check previous page, the reply's of JLasman, zEiTeR and Tomtom901.

It's probably just system messages, but you could look at the content.
The only thing you placed here is the header which contains this:
059 Subject: Mail delivery failed: returning message to sender

Check the content of that messages. Is it a system message, spam, something you don't know. Because your system is originating it and you have to look if it's legit.

thank you, the problem was fix,
But I want to know , All domain name in my server. and the sender was [email protected]
but how can i chage to [email protected]?

You have to create the "yourdomain.com".
If you did, you have to authenticate with username/password for the "yourdomain.com" to be able to send mail from it.

But take care. They should be seperate useraccounts.
If mydomain.com and yourdomain.com are both registered under username, then the main mail will be send from mydomain.com.

If you want to send mail from yourdomain.com in that case, you have to create a seperate email address in yourdomain.com like [email protected] in DA.
This will then get a seperate password too which makes you able to authenticate in the mailserver for yourdomain.com.

Maybe there are other methods, but this is the most easy one according to me.
I hope you understand the explanation.

I have a server and I have many users(different domains)
But I was check the mail server's log, I don't know they send(all users) mail by my domain(through PHP's mail).
But the old server's format is: [email protected]
but now is: [email protected]
