i know how to use telnet for sending mail via smtp

run... "cmd" enter
"telnet mail.blabla.com 25" enter
"helo aname" enter
"mail from:aname@server.com" enter
"rcpt to:aname@server.com" enter
"data" enter
"bla enter
bla enter
bla enter
." enter
"quit" enter

that is not the problem, i'm looking for a server (telnet mail.blabla.com 25) from where i can use any fake or real account to send the mail from (mail from:aname@server.com)
on the hotmail server (mx4.hotmail.com) the only working address i tried was bgates@microsoft.com, strange because filling in my own address (vincent_griezelig@hotmail.com) or any other hotmail-address fails...

telnet tells me the mail is send, but i don't recieve it (the mail from Bill ends up in my spambox, but i recieve it...)

I also want to know what to type after entering the "data" command...
e.g. subject:, from:, to:, how many spaces, enters etc...

thanks vincent
