RE: “Your message to system@sent-via.netsuite.com couldn’t be delivered”
Has anyone seen an error like this before when replying to a NetSuite email address? It started out of the blue this week, so far it only occurs to our internal employees sending from Outlook 365.
Basically you’re going to have to talk to your email administrators to get it sorted. “Reply from customer/vendor received > From email address is “system@sent-via.netsuite.com”” SuiteAnswersId: 78277, “Undelivered Emails Saved Search” SuiteAnswers Id: 64668, and “Email Best Practices” SuiteAnswers Id: 9429 are good places to start if you need more detail for them.
The fact that you are receiving emails from system@sent-via.netsuite.com means one of the following:
- You don’t have DMARC/DKIM setup for your domain (which you should do, if you haven’t)
- The email is coming “from” a domain you do not control
Fixing the above may resolve the error or it may be something in your email setting or in the email settings of your recipient that is causing the issue. A quick googling of your error code indicates to me that it’s likely on the recipient side, as does the fact that this issue started only recently.
Actually the emails do show the customer email, followed by system@sent-via.netsuite.com (which I think is correct?)
When replying to the email, it also shows the customer email address, but really sends to system@sent-via.netsuite.com.
I setup DKIM and the report indicates it is working:
SPF check: none "iprev" check: pass DKIM check: pass SpamAssassin check: ham
However the issue persists.

Okay, glad those are working. Sounds like it’s definitely something on the recipient side as that error code indicates then. Contact them and ask to get in touch with their IT department/email administrator if you’re really keen to track it down.
