I am running VPS server running CentOS Linux 6.3, Webmin 1.59, and Virtualmin 3.94. For now, I only host one domain but planing to host 3 more domains. I need someone to help me config Postfix to use Virtual Mailboxes and Postfix mail user to use username as emailaddress and config Postfix to run multi domains.
Someone with experience with the webmin control panel please, and someone reliable
