Subject: Deliver anyway (don’t obey quotas)
So… you want users to get mail even if they are over quota, but you want them to KNOW they are over quota and have to deal with the hassle of a warning if the choose to do so?
I’m assuming you’ve done a bit of work with your server’s configuration settings. In those settings are a Router/SMTP tab, under that a Restrictions and Controls section and finally Delivery Controls.
What you should do is first, set up the mail files with a quota and even a warning threshold. Personally, I would recommend you push them to archive or clear old docs off the server and get under your desired quota, then set the databases and go. You may have to take that tough love approach because there are always going to be people who are “too busy” to take the time to do even minimal cleanup. If you want to proceed without stopping mail for abusers then they will probably go over quota and never bat an eye at it.
So… set your quotas/warning. The go into those delivery controls and make sure the “Over warning threshold notifications” is set to something (per message or interval). If you set it to per message, it will be a serious nag, if you go per interval, it could be a serious nag. We set ours to act daily.
You can tweak these settings for warnings OR for quota… so if you opt to go with no warning level and just a flat quota level, be sure you’ve got the correct thing configured.
Obviously you’ve probably seen you can either deliver mail if users are over quota, set it to immediately deliver a failure to the sender OR hold the mail and retry. Last method gives them a little time to cleanup before failing back to the sender, but if they are the kind who ignore the warnings but pay attention to the users, this method will only slow down how quickly they realize the have a problem.
My experience with this is that if you have it setup correctly the users will get errors when sending mail as well as on your interval.
Don’t mean to preach… you know your users and the grief you’ll get better than I do, but just from general experience, there are always stubborn abusers who ignore sensible practices.
If I’m missing the mark on your question, let me know… wasn’t sure if you wanted to just bug the users more to encourage them to reduce or prevent them from sending, but not receiving, etc.
