Vexim3 Questions

I'm working on setting up a new server due to hardware upgrades and started
looking into upgrading vexim.  I'd played a bit with version 3 earlier this
year and liked the starts of it.  Well, to make a long story short, it's not
working on the new system at all and I'm not sure why.  I had it working on
a machine I'd been setting up back then but now it's chucking errors:

<ERROR ON ATTEMPT TO SYNCDB>

cygnus:/srv/daemons/vexim# python manage.py syncdb
Traceback (most recent call last):

    type = models.CharField(maxlength=16)
TypeError: __init__() got an unexpected keyword argument 'maxlength'

</ENDERROR>

I wasn't sure if anyone knew what might be going on here, if it's totally
just hosed or maybe it was something silly I did.

Python Version: python/lenny uptodate 2.5.2-3
Django Version: python-django/lenny uptodate 1.0-1

Any help that anyone might be able to lend on this would be most
appreciated.
