Configuring Mail Delivery Settings
Virtual Mappings
Virtual Mappings are used to redirect mail addressed for one domain to a different domain. This
process is performed without modifying the To: and From: headers in the mail, as virtual mappings
modify the envelope-recipient address.
For example, ePrism can be configured to accept mail for the domain @example.com and deliver it
to @sales.example.com. This allows ePrism to distribute mail to multiple internal servers based
on the Recipient: address of the incoming mail.
Virtual Mappings are useful for acting as a wildcard mail mapping, such as mail for example.com
is sent to exchange.example.com. You can create exceptions to this rule in the Mail Mappings
for particular users. Virtual mappings are also useful for ISPs who need to accept mail for several
domains, and situations where the envelope-recipient header needs to be rewritten for further
delivery.
Note: You should review the use of Mail Routes before setting anything in Virtual
Mappings, as they may be more appropriate for delivering mail to internal mail servers.
Configuring Virtual Mappings
Click on Mail Delivery -> Virtual Mapping on the menu to configure mappings. Click on an
