The host 'SMTP' could not be found. Please verify that you have entered the server name correctly. Account: 'HTTP (1)', Server: 'SMTP', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 11001, Error Number: 0x800CCC0D

As the message says have you checked to make sure the information you have for the outgoing server correct?

Often I see this message caused by Norton AntiVirus. If you have that installed try turning off the email scanning and then try to get your mail.
