|If you wish to have exim send an warning to your email users when their inbox is reaching it's limit, edit your /etc/exim.conf, find the virtual_localdelivery:, just below the line that begins with quota = add:|
quota_warn_threshold = 80%
Save, exit, and restart exim.
NOTE for SpamBlocker 4.x+:
If your "virtual_user" director uses LMTP (transport = dovecot_lmtp_udp), then the virtual_localdelivery will never get called, so the above guide won't apply.
When using LMTP (all new SpamBlocker versions), any E-Mail quota notifications would need to be done through dovecot's quota warning system:
A guide has been created here:
|Force immediate bounce of email if account is over quota|
|LMTP quota limit notifications|
