All that unnecessary quota activity. *sigh* Again with the missing the obvious. All I am pointing out is that once you have accepted a message, you are wasting your organization's storage and resources already, so I don't really see the harm in dropping it in the user's mailbox and incrementing their quota information. > > The point is to know that the user's mail box is full and _not > > accept any more_ messages for that user. > > You are arguing against providing a safety net.

The sender gets a DSN saying "Sorry, your mail didn't get delivered" either way, right?

Since exim can do arbitrary lookups in a number of backends, it would be trivial to store quota information in sql, ldap, flat files or cdb on shared storage, or whatever other signalling mechanism you can think of to communicate state. As for config file snippets, the first hit on google for 'exim quota sql' takes you to a discussion of how to implement it. I look forward to another qmail installation disappearing. It seems to be one of the primary agents of backscatter spam on the public internet. You seem to be conflating unavoidable DSNs and DSNs created due to software or admin created constraints. They are not the same. -- ----------------------------------------------------------------- | ,''`.
