I have a Groupwise system that recieves more than 1 internetdomein.
For example;

aa.com bb.com and cc.com

user X just need aa.com and bb.com to recieve mail from
user Y want just bb.com and cc.com
user z want just aa.com and cc.com.

Can I configure this in Groupwise 8 ?
I can install more POA's when needed.(als more gwia's)
