troubleshooting outbound smtp
Posted on 2014-03-11
I have a couple of multifunction printer/scanners. Until recently, these scanners could scan to email without issue. Now, no messages are being received. We use the Office365 exchange service if that helps. I verified the SMTP service is running on our internal relay. I ran a telnet test from the SMTP server, and the test mail is queued for delivery. The message sits in the queue folder for a moment and is gone. The message is never received. It does not go to the Badmail folder. Nothing is being generated in the smtp logs folder. I've tried sending a test message to my domain email account, and an external account. Neither receive a message. Appreciate any help from here.
