- Plesk 12.5 for Windows
- Plesk Onyx for Windows
- Outgoing Mail Control is not blocking email messages which exceed the defined limit;
- Outgoing Mail Control Statistic for subscription is not counting sent email messages;
- Mail messages are sent via MailEnable webmail.
Messages sent via the MailEnable webmail are not counted against the corresponding subscription's outgoing mail limit, because they are placed directly into the mail queue bypassing Plesk.
Install and use another webmail, for example, Horde webmail.
