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: email@example.com
- Type RCPT TO: firstname.lastname@example.org
- Type DATA
- Write something like This is a test message
- Type . (dot) and the press return. Your test message should now be sent correctly.
