Problemer med at sende email til website

Hej Eksperter,

Jeg har fulgt nedenstående tutorial.
http://www.asp.net/learn/videos/video-46.aspx
Det starter 11.30 min inde i filmen.


Alt virker fint indtil jeg skal sende min email. Den del af tutorialen som jeg ikke kan få til at virke er hvor man skal sende mailen.

Jeg har connected den til en mail på mit webhotel.

Fejlen ser således ud. Nogen som kan sige noget?
