cpanel exim limit spam

Hello,

The following cPanel/Exim configuration will help you stopping spam in the server.

1. Login to WHM control panel
2. Goto Main >> Service Configuration >> Exim Configuration Manager
3. Enable RBL filtering by Basic Editor >> RBLs >> switch to “On” and if you like you may additional RBL from manage option.
4. Enable Sender Verification by Mail >> Sender Verification >> “On” this will check if the mail origin really exists.
5. Reject SPF failures by ACL Options >> Reject SPF failures >> “On” this will verify SPF records and if the SPF record is set to fails then the E-mails from those IPs will be rejected.
6. Home >> Server Configuration >> Tweak Settings
7. Turn “Initial default/catch-all forwarder destination” to “fail” this will fail the catch all feature to be sent to default cPanel account.
8. “Set Max hourly emails per domain” which will limit the E-mail flooding from the server(I normally set it to 70 which is good enough for a single domain for an hour).
9. Set “Maximum percentage of failed or deferred messages a domain may send per hour” everyone knows that Spam E-mails will have alot of non existing E-mail which will then be deferred so If we set this to say 50% the spamming E-mail account will be suspended temporarily if the deferred mails are above 50%.

10. Then save all the configuration this will stop most of spams in the server.

HOW-TO: Install APC Direct admin

Install autoconf:
Code:
apt-get install autoconf
Install APC using PECL:

Code:

pecl install apc
After install process we have messages like this:

Code:

Build process completed successfully
Installing '/usr/local/lib/php/extensions/no-debug-non-zts-20060613/apc.so'
install ok: channel://pecl.php.net/APC-3.0.19
configuration option "php_ini" is not set to php.ini location
You should add "extension=apc.so" to php.ini
Edit php.ini (via DA or directly: /usr/local/lib/php.ini)
modify extension_dir directive:
Code:

; Directory in which the loadable extensions (modules) reside.
extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-20060613/"
Enable extension apc.so:

Code:

extension=apc.so

How to upgrade custombuild to 2.0?
The best way to do that is a complete reinstallation of CustomBuild, because of changes in configuration files, options.conf etc. Please note that you need DirectAdmin version 1.43 RC1 at least (you can use current pre-release binaries too) to run CustomBuild 2.0.

wget -O custombuild.tar.gz http://files.directadmin.com/services/custombuild/2.0/custombuild.tar.gz

cd custombuild
../build
Please check your options.conf file, set the settings you would like to have. The following steps are needed after upgrade of the CustomBuild script, if you would like to use apache:
