imap_mail_compose function in PHP5

Hi, i've got problem with imap_mail_compose function, I have this code: -------------------------------------------- $envelope["from"]= "joe@example.com"; $envelope["to"] = "foo@example.com"; $envelope["cc"] = "bar@example.com"; $body[1]["type"] = TYPETEXT; $body[1]["subtype"] = "plain"; $body[1]["contents.data"] = "contents.data3\n\n\n\t"; echo imap_mail_compose($envelope, $body); -- but the result is only the text "contents.data3", this is not expected functionality.... I'm using PHP5.0.3 on windows, I cannot change it to PHP4, because whole project is using PHP5 functions and object model... so does anybody know, what might be wrong? The strange thing is, that I already has PHP5.0.3 installed and everything was working fine, I have to reinstall it, so I've installed PHP again and now it's not working.... Any advice? solution? Thanks Bronislav Klucka
