but think not gmail. because google mail service uses different techniques. link tls ssl,

you need library implements smtp.

for c++, suggest take @ vmime, though i'm not exclusively sure whether it's supported on windows (there's section on compiling mingw, though, imagine there's native winsock support).

alternatively, c library libcurl handles many protocols, including smtp.
