What is Database Mapping?
Database Mapping (DB Mapping) is the process by which cPanel & WHM maps the relationship between cPanel accounts and their database user, database virtual users, and databases. The DB Mapping code is responsible for Database Prefixing and assists with Account Transfer mechanisms.
Benefits of Database Mapping
The benefits of DB Mapping revolve around two key points:
• Account-database relationships are preserved when transferred from non-cPanel accounts.
• Database usernames can be the optimal length.
DB Mapping is available in all builds of cPanel & WHM 11.28 and later.
Looking for Outbound spam
Log files where we can look for more details are.
The following to the exim configuration to enable some extended logging that greatly improves the ease in tracking down on-server spammers:
In WHM > Exim Configuration Editor > Switch to Advanced Mode > in the first textbox add the following line and then Save:
log_selector = +arguments +subject
This tells exim to log the path on disk from where the email was executed and the subject of the email.
suexec, if enabled, will run CGI scripts as the owner of the script file, typically the cPanel account name.
phpsuexec, if enabled, will run PHP scripts in the same manner as CGI scripts.
The NLnet Labs Name Server Daemon (NSD) is an authoritative RFC compliant DNS nameserver. It was ?rst conceived to allow for more genetic diversity for DNS server implementations used by the root-server system and it has been developed for operations in environments where speed, reliability, stability, and security are of high importance. NSD is currently used on root servers such as k.root-servers.net and is also in use by several top-level domain registries.

EasyApache3 Saving Custom Options
Every time Apache is rebuilt, its current configuration is stored as Previously Saved Config, in both the command line and WHM EasyApache interfaces. However, you may still want to store your custom configuration for later use.
To store custom options, you should save the configuration with a file name, display name, and description. You can accomplish this under step 6 in EasyApache, by filling in the required information and clicking Save and build or Save only (Do NOT build). Using the Save only (Do NOT build) button can be useful if you would like to create a profile for a different server.
The custom profile is saved to the
/var/cpanel/easy/apache/profile/custom/
directory on your server, and automatically given the filename extension .yaml.
