Toshiba Equium laptop?

How can I "e" mail as Ican't sign in, send or receive messages. Have altered my settings to allow all cookies as a message came up saying please allow more cookies or you will not get in.
Also says server not found try later each time, have 7 messages typed in but will not send, also says invalid "e" mail address. This was in NTL WORLD.Com so signed into MSN and went into HOTMAIL .Com but still no server.I can only type into How To Mend It.com and get a reply. Can anybody help as I cannot contact my daughter only by phone?
