Hi Oluyomi , I am not an expert in Windows . I am working in LAMP platform . So I may be wrong too . So these are the trials that you can run ... Can you send a simple mail like mail( $to , $subject , $matter ) ? If you get this mail fine, then its to the $header you have added . Else as Mr X ( I don't rmbr his name I think its Joe ) told its problem configuring the mail server . Let me know whether a simple mail works for you ........

The application has been deployed and running effectively. The only proble is that sometimes the mails stop delivering. When the form is submitted it displays that the message has been sent but it is not delivered inbox of outlook mail. This has happened several times and sometimes i just tweak and restart the iis then it starts working. this time around, it has not come up, i'm looking for a lasting solution. Any recommendations please? [Non-text portions of this message have been removed] Now surf faster and smarter ! Check out the new Firefox 3 - Yahoo!
