Problem after closing open relay on exchange 2003

I found I had on open relay on a Exchange 2003 box and after changing the default SMTP virtual server properties by unchecking 'Anonymous access' I'm not receiving any inbound emails for external domains.
I've taken a look at the SMTPSVC1 logs and they are being rejected with a 454
Any ideas anyone?

You need to allow receive from anonymous, just not allow submit or relay by anonymous

Ah, I understand now.

Many thanks
