MX record about fmtechnologies.com exists.
Connection succeeded to mxin.name-services.com SMTP.

5.4.4 is FAILURE TO ROUTE - it's a PERMANENT ERROR and will fail delivery.
The recipient's MX server may have had DNS issues at the time and could not be found.
See: E-Mail Delivery Error Codes to learn more about non-delivery.

I got this when sending using SmarterMail but using Yahoo Mail, it's delivered successfully and even got a response from the recipient. What could be the issue?
