- 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:
C:\Program Files (x86)\Mail Enable\Logging if this is a fresh Plesk Onyx installation
%plesk_dir%Mail Servers\Mail Enable\Logging if this is a Plesk Onyx installation upgraded from previous Plesk releases
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:
