I used a PHP mail function- and it work's perfectly on my computer...
However when a friend tries it, or any other computer, I'm not receiving any E-mail.

Is there any reason for this?

Does the server that the script is on support/has a mail server on it.

also, a code snippet would help

if the web server runs on a windows computer, he must alter the php.ini file to specify the smtp server and username/password to use to send a mail.
http://www.php.net/manual/en/mail.configuration.php

My server Is running under Linux.

How do I adjust/specify sendmail path or SMTP or whatever it is I need to do?
(SMTP is now "localhost")

You need to set up a mail server and then set your php.ini to use that mail server.

You don't. PHP use the "sendmail" binary on linux. On Windows, as this is not available, it requires to have an smtp server defined in php.ini to handle those mails.

But of course, if you have an mta (postfix, sendmail, exim) installed on your server, it will use it, as they usually installs wrappers for "sendmail".

The trick is that if the server of your friend is Window based, he need to adapt php.ini to specify the smtp server of his ISP.
Your server being Linux based, you don't need to alter anything.

Thanks everyone for all the advice...
I switched this onto another one of my sites (hosted on the same server)
and it works on that site.
Why would a mail script work on only one of my sites?
The new site (the one it works on) is actually a reseller so the one it DIDN'T work on is hosted 'through' it. Is there any way that maybe when i created myself the package I didn't give my site 'permission' to use the protocol or something?


and for future reference how do you adjust/set-up the php.ini?

Its the server's Operating System, Linux doesn't require any settings changes, while windows does.
