IMAP Hijinks

I'm running Intenet Security 2012, and Win 7 64-bit.

 

Gmail Account Information shows a bunch of unexplained IMAP connections to my computer.  Always in the middle of the night when the computer is on, but not in use.  The IP address is not the same as my regular IP address.

 

I am not using Outlook, etc.

 

Please tell me what is going on.
