I have many sites that use a custom vhosts.conf file to set alternate DocumentRoot to a directory. The Directory holds a script that reads the server_host variable and serves content from a common database but tailored to the referring "site". These phantom sites have only dns zone - set up though WHM, a custom VirtualHost entry for port 80 (web) and a custom VirtualHost entry for port 443 (SSL) (placed in a custom conf file). They are not actual accounts in the sense that they are not set up as new accounts in WHM.

Im wondering if there is a way to set up email accounts for these phantom accounts?

Below are my specs:
WHM 11.2.0 cPanel 11.11.0-S16715
CENTOS Enterprise 4.6 i686 - WHM X v3.1.0

Thank you

Is the system sending mail already ? If so, how, and what is the setup?

Details about the mail environment are important.
