spoofing

Masters,

Unfortunately we got some spam mail which seems to be coming from our own domain.

I found some article which all says to remove Anonymous login from internet receive connector

(http://exchangepedia.com/2008/09/how-to-prevent-annoying-spam-from-your-own-domain.html)

I think i something misunderstood about those articles, because if i remove the Anonymous connection e-mails did not receive from external address (like gmail - Diagnostic-Code: SMTP; 530 5.7.1 Client was not authenticated)

Some pictures about our configuration:
