Assigning an owner to alias list for virtual email domain!

[honey bee]

Hello,

The owner-list option works for /etc/aliases, but it doesn't work for /etc/vmail/aliases.DomainName, which is my virtual email domain alias file.It delivers the mail to the defined list in /etc/vmail/aliases.DomainName but doesn't bounce back the error to defined owner in case of virtual email domains.

Is there any particular setting required for it?.I want to assign an owner to the list for virtual domain.How can i do that?
