foreach array into mail isn´t working

Hello people, I got this script: <? $maildb = file("mailaddr.txt"); foreach ($maildb as $address) { mail($address, "THis is the subject\n", "This is the message\n", "From: josepablo@net.co.cr\n"); } ?> The mailaddr.txt looks like: addr1@server.net addr2@server.net addr3@server.net However the script does send mails BUT they look like this: From Nobody <Root@myserver.net> To addr1@server.net Subject [No Subject] **From here down is the message body*** Subject THis is the subject From: josepablo@correo.co.cr This is the message Anybody have an idea why?? I tried it on 2 servers running PHP4 doesnt work, however i also tried using the mail(...) i used up there but alone and that does work.. so the array is screwing something up.. Josepablo Pérez
