Setup Exchange 2013 /2016 Receive Connector

Written by Allen White on. Posted in Exchange 2013, Exchange 2016

In exchange 2013 and Exchange 2016 out of the box once you have setup your send connector and your Exchange 2013 or 2016 accepted domains policy you need to enable your default receive connector to accept external mail as if left it will only allow internal email. This is a simple process. First in the EMC/EPS select Mail Flow.

You then need to select the Receive Connector option.

Once done you will see a list of receive connectors on your domain, the one we are interested in is the DEFAULT-FRONTEND-SERVERNAME which is classified as frontend transport as seen below.Here is an explanation of the new roles for receive connectors


  • Default FrontEnd <server name>   Accepts connections from SMTP senders over port 25. This is the common messaging entry point into your organization.
  • Outbound Proxy Frontend <server name>   Accepts messages from a Send Connector on a back-end server, with front-end proxy enabled.
  • Client Frontend <server name>   Accepts secure connections, with Transport Layer Security (TLS) applied.

Highlight your Default Frontend SERVERNAME and select edit. You will see the screen below. Then select security.

We then need to select Anonymous, this enables any users on the web to send email to your domain.


Your new Exchange 2013 Receive Connector is now setup to accept email.

    HI Allen!

    Thanks for your topic. And in my case, I have 3 CAS/MB server so in ECP, how can I config the Default Frontend SERVERNAME? Does I need config all Default Frontend SERVERNAME on 3 server?

      Hi Banjo, Send connectors are org wide however receive connectors are server specific. So if this CAS/MBX server is internet facing you would create the Default Frontend receive connector on it with anonymous access so it can accept email from outside the org. On the servers that are not internet facing you simply create the Default Frontend withe Exchange servers and any other connection permissions they require.

      Hope this helps

    Hi Allen,

    I have an exchange 2013 with the same set of permission on the Receive connector Default Frontend EXCHANGE2013. However i’m getting event 1035 with external unknown IP’s like [173.166.93.225] and [69.84.26.106].

    These IP’s are blacklisted in mxtoolbox.

    Can you please share a light on this and let me know how to fix this issue or we can safely ignore these events.
