Hello, firstly, I am not a wiz at this so please keep things simple and apologies if even the question makes no sense! Here goes...
I have a site running on a virtual dedicated server running windows server 2003 and plesk.
The site is in php and has a rostering system. When a logged in user whose email address is a company one (same domain name as the website) it returns this error...
Warning: mail() [function.mail]: SMTP server response: 550 Requested action not taken: mailbox unavailable or not local in C:\Inetpub\vhosts\eventparamedics.co.uk\httpdocs\objects\class.Mail.php on line 47
Any advice on where I should be looking to fix this?
Finally, the whole process is confused slightly by the fact that the v-ded server is with goDaddy and all email is handled by server101.
Any advise on this would be great.
