Change "From" Name of Resource

Hi,
I created a new Resource called xxx with corresponding Email-Address xxx@mydomain.com.
I set up a rule which auto-replys for this resource.

Now in the Email which is sent by the reply rule the from field looks:
xxx xxx <xxx@mydomain.com>

Can I change this somewhere?

Inside the rule the "From" Field seems to be ignored... (Groupwise 2012SP2)

Best Regards
