All Freedom server products can have multiple domain names associated with them. Using multiple domain names on a virtual server is called Virtual Hosting, and is explained in the Hosting Multiple Web Sites chapter.
Email accounts and email aliases apply to any and all of the domain names associated with your Freedom account. For example, if the domains 123.com and abc.com both point to your Freedom account, an alias on your Freedom account called "webmaster" will redirect mail sent to both webmaster@123.com and webmaster@abc.com.
However, what if you want webmaster@123.com to go to a different account than webmaster@abc.com? The solution is to use a Virtual User Table, or virtusertable.
A virtusertable entry is similar to an email alias, in the sense that it points one email address to another. There are, however, some very important differences between the virtusertable and aliases:
Virtusertable entries are located in a separate file than email aliases. Both files are located in the /etc/mail directory, but aliases are stored in a file called aliases, whereas virtusertable entries are located in a file called virtusertable.
A virtusertable entry must be defined as an entire email address (including the @ and the domain name), followed by a space or tab, followed by a destination.
Unlike an alias, a single virtusertable entry cannot point to multiple addresses. A virtusertable entry can, however, point to an alias that in turn points to multiple addresses. A virtusertable entry can also point to an email account, another virtusertable entry, or a complete email address located on another server.
IMPORTANT NOTE:
If using a catchall, you cannot use a fully qualified email address pointing to an address on the same domain. For example, the following catchall will cause excessive recursion errors:
example.com bad@example.com
All of our packages allow you to add as many entries into your virtual user table as you like. You can also add a special type of virtual user known as a catchall, as explained in the Using a Catchall section of this guide.
