[Mailman-Users] errors using DELIVERY_MODULE = 'Postfix'

Whe i set DELIVERY_MODULE = 'Postfix' i get the following error repeated several times on the console.

Traceback (most recent call last): File "/var/mailman/bin/qrunner", line 270, in ? main() File "/var/mailman/bin/qrunner", line 217, in main qrunner = make_qrunner(*runners[0]) File "/var/mailman/bin/qrunner", line 123, in make_qrunner qrunner = qrclass(slice, range) File "/var/mailman/Mailman/Queue/OutgoingRunner.py", line 57, in __init__ mod = __import__(modname) ImportError: No module named Postfix

What is missing or what is wrong? I can send to the list and stuff gets posted but messages don't get sent out. I have been trying with DELIVERY_MODULE = 'SMTPDirect' but that didn't work so since i'm using postfix i decided that would be another option. But i get the above error when i start mailmanctl.
