In whatever transport you use to deliver mail to your users, add the line quota
= 5M (sets user message quotas to 5 megs).
For spam blocking, use the RBL and other blacklists
rbl_domains = rbl.maps.vix.com:dul.maps.vix.com
recipients_reject_except = postmaster@???:abuse@???
rbl_hosts = !192.168.1.0/24:!mail.example.com:!example.com:0.0.0.0/0
rbl_log_headers
rbl_log_rcpt_count
Also maintain a local blacklist of spammers
sender_reject = @@lsearch*;/usr/exim314/blocked.senders
blocked.senders is of the format
aol.com SuccessisGreat:SuccessisGood
mailgate.lifeminders.com *
AnywhereYouGo.com *
gslot.com register
smtp5.dailydirt.com *
ralph.dailydirt.com *
mailbits.com *
* admin__
[that last line is to get rid of the 'M$ Y2K Fix' trojan which remails itself
