Problems sending emails through outlook.

Hello,

I am having problems sending email not with my yahoo account but through outlook or when im on another website. Whenever i try sending an email the response that I recieve is as follows:

The host 'SMTP' could not be found. Please verify that you have entered the server name correctly.
Subject 'Receptionist Position', Account: 'Pop3', Server: 'SMTP', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 11001, Error Number: 0x800CCC0D


Can you Help? Please
