Protect Against Spamming

[bryzo]

How can I make sure that my users are not spamming through WHM? Is there a way to restrict the amount of emails being sent per hour or sent at a particular moment?

Thanks!

The setting is in

WHM -> Server Configuration -> Tweak Settings -> Mail

listed as:

The maximum each domain can send out per hour (0 is unlimited)

Other things you may wish to do:

- Use SuPHP and SuExec, then disable the nobody user's ability to send email via Tweak Settings
- Enable the SMTP tweak in Security Center.

You really need to set the max email per hour setting in WHM to something low. This will really prevent spamming. You also need to monitor outgoing mail to see how many emails scripts are sending out.

you might also want to add the 'Mail Headers' patch to PHP from easyapache, as when mail is sent from PHP it appends the script that sent it and the IP of the person who triggered the send to the mail headers - very useful for tracking down spammers

Can you just confirm this is here:
Main >> Service Configuration >> Exim Configuration Editor
Mail
Set the Sender: Header when the mail sender changes the sender (-f flag passed to sendmail).

In WHM, go to the Software section and click Apache Update.

If prompted to upgrade, do so and after that has completed, try again.

Proceed through the process until you get to step 5. Then click the button for exhaustive options list. Now, scroll down and check the box for "MailHeader" and then click the button at the bottom of the page to begin the compile process.
