DNS Error sending email

[richs]

I have a customer with an OKI ES8473 and an OKI MPS5502 that would not send email using Office365.I managed to be able to get the machines working using gmail on port 465.They would not work using port 587.The customer was convinced the the machines were at fault.The problem now is both email but the ES8473 comes back with a DNS error.I have tried different DNS servers and even tried using the IP of gmail SMTP server.I am convinced that it is a problem with their network but the customer is not buying it.Even thou IT work is not covered I doubt they will pay their bill when they get it.Any suggestions?

The MPS5502 series machines were released in 2013, so it it likely that it would require a firmware update in order to communicate with the updated SSL/TLS settings in Office365. I'm not sure of the age of the 8473, but if it's before 2018 then flash that one as well.

Micro$quash has been the bane of a copier tech's existence for the last year now!! Killing SMB v1, increasing SSL/TLS encryption security for email... They... along with Google, are making our jobs a little harder.

Agree with updating the firmware. And also, check with the manufacturer if it's all worth it to upgrade as port 587 is used by STARTTLS.
This happened to me on a MPC300 ricoh device.

If gmail works clearly the machine is not at fault.

Update the firmware you’ve then covered yourself pass it back to IT

To answer a few questions the error is only on the ES8473....so what they run on their computers does not matter.It only says DNS error please check setting or contact your administrator.They do have an IT guy but he just keeps insisting it the machines.Bo the machines are emailing now using gmail on port 465.There is an update on the ES8473 I can install but it has nothing to do with email or DNS(its to fix printing errors) I will probably do it thou.

t would help if you were to tell us what the DNS settings currently are and if they are the same for both machines.

Use the customer's MX record as the SMTP server on port 25 with no authentication. Put their domain into the following link:

MX Lookup Tool - Check your DNS MX Records online - MxToolbox

Same on both machines.Also tried google DNS and Open DNS.
