Could you share with us what you've done?
This is my own installation from home, hosting 3 other domains and mine - all very modest.
Noticed the following after a default install of eGroupware as per the Wiki:
Virtual domain users are presented with a log in to eGroupware just the same as primary domain users.
Virtual domain users inherit the title name of the site set in Admin>Site Configuration.
Say I change the title to "mydomain", and a virtual user goes to
http://virtual_domain.com/egroupware, the browser's title changes to "mydomain"
Presumably then, all other settings will be inherited?
At this stage, and being quite new to SME (excellent software) and to eGroupware (excellent contrib), I don't know if this is desireable or not - e.g. the virtual domain client will have to notify me of a new employee or I must give the client access via user panels. This may be a security hole.
Fact remains, as long as a user has a SME account, he can have an e-mail account. For my (mainly experimental) installation, this is good enough.
What I've done is nothing special and doesn't warrant inclusion in the Wiki, I'm sure
