How to prevent client spam mail?

[waterkei]

I have some client in my host and running some eariler(OLD) php script. These kind of script may be hacked by other user and outspam of the system.

How I can know (Using which command) I can know is the client or hacked user to spam mail by the server?

I have installed the spamblocker in da, can I input my client domain in the Block_sender_domains ? Can it solve?

You can learn spammer tricks and try them yourself against every form on your server.

Or you can watch your logs. When you see a lot of spam going out you can tell from the logs which user is sending it by username. The username relates to one or more domains on your server.

That's not a good idea since it will prevent your client from sending any email at all to your server, including any email your client would send you.

You'd be better off blocking the specific sender, [email protected] where username is the username on your system (not any specific email address, but the username that owns the domain).

I'm not sure yet if this will work or not; I'll do some tests later today.
