status=sent , but 1 DISCARD

Good day.
I have a database on a different server Zimbra Network Edition. The server of the database via a Send an e-mail sent by certain information to zimbra account, this account does not copy a forwarding two user accounts, but one does not get the message.

If I send an email to this account makes forwarding from another account outside or inside the domain if the message reaches them both accounts.

That is happening because if you send from the server to the database it does this is the little information I have from the logs.
