Show Email activity in Logs

Hi, I'm trying to look through the History in the GUI to see if email is being sent.  Is the email sent/received logged anywhere...? 

 

I'm going to guess that SPAM is detected and logged in the antiSPAM log but it's the "real" email I'm interested in. 

 

I have a vague memory that earlier versions logged it, so it's either been removed totally or hopefully it's still logged but a default setting that I can't find has been changed...
