We recently installed SBS 2003 Std. and in Exchange we have messages destined for a particular domain that will not go out. If I fail the messages I receive the following NDR:
This message was rejected due to the current administrative policy by the destination server. Please retry at later time. If that fails, contact your system administrator. <#4.3.2>
This is default install.
I have seen some solutions referencing this error, but they appear to apply to EXCH 5.5 migrations, not fresh installs.
