System processing trying to connect to smaddison.plus.com

Hi,
My Comodo firewall showed the the System process was tyring to connect to "smaddison.plus.com " using a POP protocol (port 110). For now, I have blocked the access by putting a firewall rule – but can someone tell me why and who is trying to connect to that from my computer? Firewall logs wont tell much apart from System process.
Appreciate help!

POP is the protocol for receiving email. So, it looks like something on your system is either trying to download email or, more likely, checking to see if you have any email. Do have anything like that on your system? Also are you sure about the name “smaddison.plus.com”?
