it looks like the web site is getting it's information from the localhost vs the domain. Where is the configuration for email at? i looked at email.php but cannot see where it is getting the information?

 

i have read many posts about this problem but i haven't been able to fix this

i am using the sendmail from my isp

mail from the isp mail accounts works fine i am able to send emails to anyone without the errors
