distribution list, list of member

[Marc Cuypers <mozilla@mgvd.be>]

Hi,

I'm using openldap to distribute info about persons (e-mailaddresses, 
addresss, ...).  This data can be used in outlook en thunderbird.

I know this question is asked many times, but I can't find a definitive 
answer to it.  How do I create a distribution list in openldap so that 
the email clients see it as an distribution list?
Sending a mail to the distribution list would expand the address to all 
members of the list.

Best regards,

Marc
