If I understand correctly it's just the one email account on this server that is having this issue and you can send emails fine to other users on the server? If this is the case I find it unlikley the smtp settings on your email client would be the issue.
Has the account got any sort of forward on it to another external email? I've seen this happen if the server tries to forward the original email to another server and it's the other server that's throwing the bounceback because it's trying to relay.
Also check transport logs, see f the client has any rules setup in Outlook, etc.
