This works well for inbound emails.</div><div class=""><br class=""></div><div class="">I would like to set up something similar for outbound email, i.e. if a user is over quota, they should not be allowed to send new emails. At the moment, the setup is in a bit of an inconsistent state: Users that have exceeded their quota are still able to send outbound emails but saving them in their Sent folder will fail leaving them without a copy.</div><div class=""><br class=""></div><div class="">I have tried using Dovecot’s quota-status in Postfix’s smtpd_send_restrictions but didn’t get this to work. A quick look at the Dovecot source code seems to suggest that the quota-status plugin is only checking the recipient address: <a href="https://github.com/dovecot/core/blob/master/src/plugins/quota/quota-status.c#L135-L146" class="">https://github.com/dovecot/core/blob/master/src/plugins/quota/quota-status.c#L135-L146</a> and <a href="https://github.com/dovecot/core/blob/master/src/plugins/quota/quota-status.c#L109-L111" class="">https://github.com/dovecot/core/blob/master/src/plugins/quota/quota-status.c#L109-L111</a>.</div><div class=""><br class=""></div><div class="">I suspect it’s not possible to use the quota-status service to control outbound email but thought I’d ask to confirm. I’m wondering if there’s a different way to achieve this?</div><div class=""><br class=""></div><div class="">Thanks</div><div class="">Peter</div></body></html>
