Virtualmin

Hi All,
I use virtualmin to manage e-mail system consists of one main domain and 10 sub-domains. including 200 email accounts for 11 domain names.

System configuration
Webmail (mail client to access users): Roundcube 0.9.4
OS: 6.4 cent0S
Virtualmin GPL version 4.06.gpl
Webmin version 1.650

  1. How to configure virtualmin created in the address book? when users access their webmail can send any one of the 200 accounts that are available on the system through the address book.

  2. When creating a new account on the system, this account automatically updated on the user’s address book in webmail.

Thanks all.
