Can't Acces Mail Server

Hi. I have some code that connects to a SMTP server and mails some stuff. The SMTP server is apparently working ok. I tried it with an email client and no porblem but when I send with the mail command i get this error on the server. un 22 15:49:05 www sendmail[31157]: PAA31157: ruleset=check_mail, arg1=<www.foo.com>, relay=[204.22.171.3], reject=553 <www.foo.com>... Domain name required I know this is more a sendmail problem. It use to work OK but now I get this problem! It seems the mail command is sending a mail with the domain as the user and no domain. This is my php.ini (NT) [mail function] SMTP = foo.com ;for win32 only sendmail_from = sam@foo.com ;for win32 only sendmail_path = ;for unix only, may supply arguments as well (default is sendmail -t) Can anyone help!!!
