How does a virtual domain differ from a domain?
6.1.2 Virtual domains
Note: This section describes how to integrate Mailman with Postfix for automatic generation of Postfix virtual_alias_maps for Mailman list addresses. Mailman's support of virtual domains is limited in that list names must be globally unique within a single Mailman instance, i.e., two lists may not have the same name even if they are in different domains.

What I'm looking to do is to use postfix "vanity domains". A vanity domain is the same thing as a virtual domain? These are syntactically valid domains:
"Postfix on hosts without a real Internet hostname
This section is for hosts that don't have their own Internet hostname. Typically these are systems that get a dynamic IP address via DHCP or via dialup. "

Such as those available for free from no-ip.com? On no-ip.com it's just called a host, and you can add hosts from a drop down of domains which no-ip.com owns. I would call it a sub-domain. The lingo is throwing me a bit.
In this event, just enter the FQDN from no-ip.com into mailman and let postfix handle the rest?
thanks,
