- Plesk for Windows
How to check why mail was not delivered to inbox?
Where MailEnable events are logged to?
In Plesk for Windows Server, MailEnable log files are stored in:
%plesk_dir%Mail Servers\Mail Enable\Logging
C:\Program Files (x86)\Mail Enable\Logging(for new installations)
Mail message passes though several stages on its way to the recipient mailbox.
Mail hits MailEnable mail server by SMTP
To track a message that entered MailEnable via SMTP, review SMTP Activity log:

Mail filter checks
Mail filter checking results (spam checks, for example) are written to SMTP Debug log. If the message was not delivered due to failed mail filter checking, it will be shown there:
