nobody@ problem with php mail()

going bananas trying to find a solution to this - my new cpanel vps will not send mail from my php scripts that work on another, same spec, vps

using php mail() results in all outbound mails being marked with return path of nobody@hostname - I have checked the Tweak Settings checkbox to disallow nobody@ mails so they are now just being discarded - all outbound mails are being discarded.

The support at the vps host just said to edit php to not send from nobody@ - like that's what I have been trying to find out how to do for hours now - recompiled apache again - still no joy - has anyone had this problem before, or more importantly anyone know how to fix it? I need to be up and running in the morning with this....

 

thanks for the suggestion - I did that just now but no luck - raised a ticket to see if I can get more help from the techs.

 

now they tell me to check for open ports - so I am scrabbling around for this now - it seems like portsentry is the firewall I am running and might not have open ports for sending mail hence bouncebacks (though why to nobody@ and not the sending address?)
