Hi Guys,

Recently install an exchange server and now the Transport Services is killing the server. I checked the queue and found thousands of these;

    This all are spam mails ,please delete those and make sure your server is not an open relay.

    Since enabling anonymous relaying on the default receive connector is a huge security issue ,i have suggest you to create separate receive connector

    Thanks Viralrathod, that worked.

    I didn't get a reply for a while and thought I figured it out myself. I did create a new receive connector and tried to run the;
    Get-ReceiveConnector newconnectorname | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "ms-Exch-SMTP-Accept-Any-Recipient"

    on it but got an error so just disable to connector and hoped someone with al least half a clue would post the answer ;-) thanks.
