Discovery does work without any boundaries defined and without the System Management container plus there's no account configurable.

I do not see any major errors in the log snippets above.

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.

A very common scenario for Exchange Server 2013 administrators is the need to allow applications and devices on the network to use the Exchange server as an SMTP service.

There are generally two specific business requirements: In this article I will demonstrate how to meet both of those requirements in Exchange Server 2013.

Simply put, receive connector selection is on a “most specific match wins” basis.

The connector with remote network settings that most closely match the IP of the connecting server/device will be the one that handles the connection.

False False As with the internal relay example I recommend creating a DNS record for a generic name for SMTP.

For most environments there is no need to create separate DNS names for internal vs external SMTP.You can just use the name of an Exchange 2013 server that is installed with the Client Access server role, or you can set up a more generic host record in DNS for them to use (which I recommend, as this makes it easier to migrate the service in future).Although the default Frontend Transport receive connector allows internal SMTP relay it will not allow external SMTP relay.Where previously the server responded with “550 5.7.1 Unable to relay”, now an SMTP connection from the IP address 192.168.0.181 is allowed to relay successfully.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] 2.1.5 Recipient OK data 354 Start mail input; end with . 250 2.6.0 <[email protected]> [In ternal Id=20005957664769] Queued mail for delivery You may be wondering how the server knows which receive connector should handle the incoming SMTP connection, considering that both the “Default Frontend E15MB1” and “Relay E15MB1” connectors are listening on all IP addresses and on the same port (TCP 25).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.Get-Receive Connector "Relay E15MB1" | Add-ADPermission -User 'NT AUTHORITY\Anonymous Logon' -Extended Rights MS-Exch-SMTP-Accept-Any-Recipient Identity User Deny Inherited -------- ---- ---- --------- E15MB1\Relay E15MB1 NT AUTHORITY\ANON...But first, let's cover some of the fundamental Exchange 2013 concepts that apply here.Looking at the Exchange 2013 transport architecture there are multiple services involved.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.
