Can anyone show me their mailbox quota part of their exim4.conf?

I can never seem to get my mailbox quotas working fine - this is what I am using at the moment:


maildir_tag = ,S=$message_size
quota_size_regex = ,S=(\d+)
quota = 20M
quota_warn_threshold = 80%
quota_warn_message = "\
To: $local_part@$domain\n\
Subject: Size of your mailbox\n\n\
This message is automatically created \
by mail delivery software. \n\n\
The size of your mailbox has exceeded \
a warning threshold that is\n\
set by the system administrator.\n"


Any suggestions are appreciated.
EDIT: I apologize for not putting this in the 'Technical Questions' forum - my bad.
