Hello all !

This is my first post on this forum.

I want help in php.

I have a linux reseller webhosting, and design and sell websites.

The problems is ...

php mail( )

mail () is not deliverying only to my domain not working when other recipients.

the send mail path is /usr/sbin/sendmail -t -i

mail('somebody@yahoo.com', 'the subject', 'the message', null,
'-fwebmaster@mywebsite.com');

That is the script.

Thank you in advance.

Problem could be lack of required headers:

$headers = "From: webmaster@mywebsite.com\r\n" .
"Reply-To: webmaster@mywebsite.com\r\n" .
"X-Mailer: PHP/" . phpversion();
mail('somebody@yahoo.com', 'the subject', 'the message', $headers);
