There are many information can be found from this page, for example the sender's and recipient's email address, email subject, date/time of mail transaction, email class (spam, not spam, whitelisted, etc.) and email status (delivered, rejected, quarantined and more).

2. Go to "Incoming" > "Logs".
3. Click on Show Results button to view the list of all incoming mail transactions.

You can carry out a variety of actions depending on the mail status in the Search Results listed on the page.
Please click on the dropdown menu next to the checkbox beside the message ID to view and apply related action to the mail.
