lmtp_overquota_perm_failure

[Robert Covell]

Is this the config option to stop emails from being delivered if they are
over quota?

We have it set to:

lmtp_overquota_perm_failure: yes

I thought I read another post regarding that it does just this.

The system does return a over quota message to the sender but the messages
still get through.

Is there something else I should look at to stop delivery, or a conflicting
config option?

Thanks,
