How to notify Plesk customers when mailbox quota exceeded?
Note: this feature is not available in Plesk Onyx
In Plesk Obsidian on Linux it is possible to enable warnings to mail users who approach their mailbox quota limit.
The notification is enabled by default on new and upgraded servers, and can be managed on Tools & Settings > Mail Server Settings.

# plesk bin mailserver --quota-warning-enable <true|false>

The mail quota notification is sent under the following conditions:
- On Dovecot, when a message is delivered to the mailbox and the mailbox size goes above the threshold mark - 95% of the mailbox quota.
- On Courier, once every 24 hours until mailbox size goes below 95% of the mailbox quota.
Note: The threshold (95% of the mailbox size) cannot be changed.
Changing notification's text is possible on Tools & Settings > Mail Server Settings > Customize the default mailbox quota warning.
Quota and mailbox size are displayed in webmail interfaces (both Roundcube and Horde):
