email_account is a helper to create e-mail accounts in a configuration
using Postfix mail transport agent with vhosts and Cyrus IMAP server, in
a Debian environment.

It allows to simply create an e-mail account and an alias for it in one
command:
 email_account me@mydomain.org my.evil.double@mydomain.org

If you don't want an alias, you can just create the account:
 email_account me@mydomain.org

You can also create an alias for an existing account:
 email_account me@mydomain.org my.clone@mydomain.org

To use this script, you have to be root, or to be able to execute
commands with root privileges through sudo.
You should install it in a directory within the PATH of the root user,
such as /usr/local/sbin.
