Symantec brightmail message filter not updating
Here is an example of what happens if I use Telnet to try and send an email to an address that is external to the organization.220 E15MB1.exchange2013Microsoft ESMTP MAIL Service ready at Tue, 1000 helo 250 E15MB1.exchange2013Hello [192.168.0.181] mail from: [email protected] 2.1.0 Sender OK rcpt to: [email protected] 5.7.1 Unable to relay Receive Connectors.
A bungled demo at a visceral level tells that the vendor didn’t adequately prepare for the product and that it is no more than a piece of crap that may not work even under the most forgiving of circumstances.The Client Access server role hosts the Frontend Transport service, which provides filtering of email traffic (eg antispam agents), and routing of email between the internal Exchange servers and the outside world The Mailbox server role hosts two additional services: Get-Service | Where Display Name -like "*Transport*" | Select Display Name Display Name ----------- Microsoft Exchange Frontend Transport Microsoft Exchange Mailbox Transport Delivery Microsoft Exchange Mailbox Transport Submission Microsoft Exchange Transport Microsoft Exchange Transport Log Search No matter whether the server is multi-role or only installed with the Client Access server role, the Frontend Transport service is the only service already listening on TCP port 25 (SMTP).The other services listen on a variety of other ports (for example TCP 2525 for the Transport service).So, if two SMTP connections are inbound, one from 192.168.0.180 and the other from 192.168.0.181, the server knows to handle 192.168.0.181 with the “Relay” connector as it is the more specific match, and handle the other connection with the “Default Frontend” connector.With the relay connector in place the ongoing management is simple.The Security market is flooded with software products, with each vendor striving hard to brand their product as the best.
It can be overwhelming for a customer to make a choice, especially when there are innumerable similar Security software solutions available on the market, with each claiming to offer something extra.
Highlight the connector and click the “pencil” icon to edit its settings. In the Exchange Management Shell run the following command, substituting the name of your receive connector.
