Since I can sent email to those servers using cgi script and from other email accounts, there is something that PHP is or is not doing that is causing the servers to reject the incoming email if you feel that is "bogus" or not a bug fine but my definition of a bug is something that does not work consistently and mail() does not.

thanks,

Please note that I am receiving an auto reply from you to yellowjacket@email.com which I am sure is being sent with PHP mail().  This would imply that you know what the problem is since your mail is being received and mine is not.

If this is not a bug it is a least incomplete documentation of how to use mail() to ensure delivery to all server types.

What is the appropriate syntax for mail() to ensure delivery?

Thank you.

your CGI is likely adding some additional headers, which is what allows your e-mail to go through. The solution would be to see what headers are sent when CGI is used and what headers are sent by PHP and use the headers argument of the mail() function to add any missing headers.

This is a problem I ran into that really had me stumped for awhile.

I was using mail() to send messages from a bulletin board I created via a form in order 
to keep users email addresses private (read no email mining possible). Problem was some 
people were not getting the messages. After testing on MANY different email accounts 
I was beginning to get stumped.

It seems that some ISP's and servers require that the Return-Path header email address 
match the From email address in order for it to be passed onto the users account. 
By adding 

-f email@address.com

as the last parameter in the mail function to the same as the From address everything 
started getting recieved as it should. Here's two examples.

mail($to, $subject, $body, $from);

resulted in some people not receiving the message.

but...

mail($to, $subject, $body, $from, "-f $from_email_address");

everyone got the message as intended.

Hope this helps someone else out as it had me totally baffled until I started comparing 
the full headers of my email messages.

To remove the X-authentication-warning put apache (or the user running httpd processed) 
into the list of "trusted users"

If you don't like the X-authentication-warning header from using the -f flag, you can 
remove authwarnings from sendmail's PrivacyOptions.

sendmail.mc: define(`confPRIVACY_FLAGS', `authwarnings,...')dnl

sendmail.cf: O PrivacyOptions=authwarnings,...
