hp.com is probably the mail server not allowing relayed mail, for anti-spam purposed. Try setting up an alias on your server in /etc/mail/aliases. eg. add in;

hp : hp.com

Then from outlook send your mail to hp@ (instead of hp.com) and the alias will forward it on to hp.com. This should get around the realy problem.
