* Original Title: Unknown Sender

I run Windows 7 and IE 11.  I use Windows Live Mail 2012 to collect my email from outlook.com and which has a hotmail.co.uk address.  When all mail to this address appears in Windows Live Mail it has a yellow banner at the top stating Unknown Sender.  My outlook/hotmail address is included in WLM's Safe Senders list.

Have seen several posts about issues similar to this but no definitive solution as to how to prevent the Unknown  Sender banner being added when mail is received in WLM.  Any ideas, please.

I should add that Windows Live Mail configured itself to use this mail server for outlook :
