Just had a customer where they weren’t able to scan to e-mail from the copying machine after changing ISP.

I fell over this article from Microsoft on howto create a anonymous SMTP Relay in a rather smart way than you used to be able to in Microsoft Office 365.  You do the following:

– Go to http://myip.dk/ and write down you external IP address. – Login to you Microsoft Office 365 portal and go to the Domains. Select your domain name and then select show DNS domain settings. – Write down the MX record that should be something like domain-name-com.mail.protection.outlook.com. – Then go to Exhange Administration. – Select mailflow. – Select Connectors. – Create a new inbound connection and fill it out with the following

  • Name: My inbound connector.
  • Sender domain: *
  • Sender IP Address: Type in you external IP address.
  • Click Save.
  • – Login to you DNS administration for you domain name and and the following to the v=spf1 ip4:X.X.X.X(External IP) include:spf.protection.outlook.com  -all – Now you’re all set. You can test it within you network by doing the following
  • Open a command prompt and type telnet domain-name-com.mail.protection.outlook.com(Your MX record from before) 25
  • Type EHLO outlook.com
  • Type Mail From: name@your-domain-name.com
  • Type RCPT TO: name@external-domain-name.com
  • Type DATA
  • Write something like  This is a test message
  • Type . (dot) and the press return. Your test message should now be sent correctly.
