I saw your post in the Zope archive regarding the imort error with NotMail. I had the exact same error on a Linux box and managed to fix it by doing the following: In NotMail.py at line 199-200, change: def __init__(self, id, title='', default_domain, smpt_server, smtp_port, imap_server, imap_port, REQUEST=None): to: def __init__(self, id, title='', default_domain='', smpt_server='', smtp_port=25, imap_server='', imap_port=143, REQUEST=None): Although I am not yet certain whether or not this modification causes any adverse effects somewhere else (to the best of my knowledge it should not as long as everything is configured properly), it does fix the SyntaxError: non-default argument follows default argument (line 199) problem. However, I have discovered more problems when I try to access NotMail, but I have not yet looked at them. I also made a modification to Connection.py similar to the one referenced in http://www.zope.org/pipermail/zope/1999-October/011505.html (knotmail) for IMAPAdapter.py (if 'NotMail' not in roles).... Anyway, hope this helps.... Regards Jarrod
