Cómo resolver el error LNK2019

Estoy enviando un simple correo electrónico en C ++. Descargué un programa de muestra de C ++ del siguiente enlace.http://cboard.cprogramming.com/cplusplus-programming/125655-sending-simple-email-cplusplus.html El programa de ejemplo parece golpear el siguiente error cuando se está compilando. Por favor ayúdame con la solución.
