That, is a toughie.
I assume you know sockets.
"Is there anyway I can connect to yahoo to load my script from my e-mail account using sockets? If there is how would I do it ? ._."
Seems rather vague - you could run a small http server, a cjb redirector (pointing to the http&mIRC server) and execute commands that way, however you'd need mIRC already running. If you wnat to start it, I advise you to use a irc:// link and let mIRC capture it. If you want neither of these things, make your post more understandable and I'll be glad to help.
