Do you see the notification

Do you see the notification in the SPM as well? Have you checked the logs on the mail server?

Re

What was the action of the SEP (AV) on the infection, is it quarantined, deleted, left alone?

Double check also the Risk Log on the client side.

I'm not sure about the last

I'm not sure about the last file, but the first 2 definitely came from the internet. If you can see which sites a user visits and test them, you'll get the infection alert.
It will be quarantined but the file will reappear whenever the user visits that site with the infected files.
