Plesk stores statistics and provides reports on attempts to exceed limits that were made by each Plesk object – mailbox, domain, or subscription. Statistics are stored for a month, but all reports are created for the reporting period - a time interval within the last month (for example, a day, two days, a week, and so on). You can configure this period in Tools & Settings > Mail Server Settings > Switch on limitations on outgoing email messages > Show reports based on statistics for the last (specify a time period).
To view reports about attempts to exceed limits on outgoing mail:
Go to Tools & Settings > Outgoing Mail Control and select the tab with the information you need:
Note: If Plesk is installed with SmarterMail, outbound mail limits are set up on the SmarterMail side by means of SmarterMail API. In this case, no filtering is done by Plesk. As a result, the mail status of Plesk objects is not available.
Also, in the Sent messages section, daily per-hour statistics are available for a certain Plesk object: You can see the number of attempts to send excessive mail for each hour of a certain day.
Note: The Outgoing Mail Control link is displayed only if the limitations are switched on in the mail server settings.
