Adding an Additional (Virtual) Mail Host

Note: Additional mail domains, virtual domains, and domain aliases can be added after the initial install. If added later, make sure that you update the DNS record according to the mail domain additions.

There are two types of virtual hosts:

• Virtual hosts with IP addresses. Recommended when you want IMail Server to receive mail for a second domain with its own users. You can set up a virtual host for the second domain. For example, if your mail server provides mail service for domain1.com, and you also want it to provide mail service for domain2.com, you can create a virtual host for domain2.com.
• Virtual hosts without IP addresses. Recommended when you have a shortage of IP addresses or when you want to forward all mail for a domain to a user at another domain.

Note: Whether you use a virtual host with an IP address or without an IP address, you must make DNS entries for your domain(s). See Setting Up DNS for Multiple Mail Hosts.
