Hello. I'm getting the following error using Outlook 2007 and Vista:
553 sorry, that domain isn't in my list of allowed rcpthosts (#5.5.3 -
chkuser)

When I test the account settings, it's fine. I can recieve just fine, and
the only outgoing messages without this error are for recepients with my same
domain.

I've turned off my antivirus and windows firewall. Still this doesn't work.

Any help would be greatly appreciated.

550 errors usually mean you're not authenticating properly, or you're
attempting to use an SMTP server other than the one your ISP provides. Most
ISPs won't allow this as an anti-Spam measure.
