I have configured my gw8 system to let the mta's deliver mail.

I can send to another external domain/po fine. But when they send to me, the mail is kicked back as undeliverable.

I've attached a portion of the mta.log file which shows

Unknown Destination: TCG_Consultiing.TCGPO

does this mean the mta can't find the domain it belongs to?

How do i fix this?
