Topic: a copy of all incoming email

[yallara]

Hi,
   I am trying to customised SME server 7 pre 3 so that all incomming mail is copied to another local user.
I am already manage to do that by modifying file .qmail-localdelivery-default inside directory /var/qmail/alias/
and adding a line "| foward user@domain...."
The problem is when someone send an email to a group.... I got multiple emails with the same content and the number of that emails corespond to the number of users in the group.

Can anybody help me in this ones? I want it to works so that when somebody send email to a group.. it only copied once and still copy the email when somebody send email to a single user.

Thanks in advance for your reply.
