Relay Connector From an External IP


  • Hello,

    We have Exchange server 2013 roll up 10. From internal network we use recieve connector for printers and scanner and then we can send e-mail accepted domains and external domains without problem.

    Also our e-arsiv system works external network. We need to send e-mail via our exchange server. I created one user then create one connector ı have added our server public IP but we can not send e-mail. 

    issue is

    "Sending email failed with Caused by: javax.mail.MessagingException: [EOF]


    Also ı run this powershell but nothing changed

    Add-ADPermission "name of connector" -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "Ms-Exch-SMTP-Accept-Any-Recipient"

    How can we solve this problem?

  • Does it function correctly inside your network?  Also, what is the domain you are trying to send from?  You should also enable protocol logging on the send and receive connectors and see what they're saying.

  • Hi,

    If you want to configure external SMTP relay connector, then add that IP address of application server instead of your server public IP. 

    Refer to this blog to Configure a Relay Connector in Exchange Server 2013
