NetSuite Professionals

Hey folks, are any of you having trouble with Netsuite email getting delivered to customers who use Office365's mail servers?  I'm getting a lot of "Permanent Failiure: Other or undefined security status" when sending mail to them.

Have you setup your DMARC and DKIM in Netsuite for the mail?

<@U2A2VHL3W> DKIM yes.  DMARC used to be good, but I'm wondering if Netsuite changing their email sending domain effected things.  Currently <http://mailsenders.netsuite.com|mailsenders.netsuite.com> is whitelisted, but I'm wondering if it needs to be the more specific domain (<http://accountid.email.netsuite.com|accountid.email.netsuite.com>)

They did change their email server lately - it could be the cause - contact support (they are useless most of the time though)

<@U2A2VHL3W> I'll try that, and yeah... they can be a bit less helpful for us especially... we don't have a support contract so unless it's an emergency *shrugs*

But considering the mail is failing delivering... I might be able to make a case for this.

<@U2A2VHL3W> Sorry, I just realized I confused SPF and DMARC when you were talking.  My DMARC is fine I think.  `v=DMARC1; p=reject; rua=mailto:<mailto:dmarc.report@MYDOMAINHERE.com|dmarc.report@MYDOMAINHERE.com>`.  But yeah... for SPF, things used to be sent from `<http://sent-via.netsuite.com|sent-via.netsuite.com>`  , then swapped to `<http://iad1.rp.sent-via.netsuite.com|iad1.rp.sent-via.netsuite.com>` in February. but are now being sent from `<http://iad1.rp.oracleemaildelivery.com|iad1.rp.oracleemaildelivery.com>` instead (as of May).  All of them are classified as SPF passes... and Outlook isn't sending me any DMARC fails... so yeah... Netsuite support it is.

<@U2A2VHL3W> Nope.  Still need to talk to support.  Will do so later today (had some other things I needed to do at work first, sorry).

Sorry, to clarify again, my SPF didn't change - their sending domain changed.  But all of it seemed to pass SPF (maybe because it matches <http://mailsenders.netsuite.com/> ).  But Office365 clients are still having troubles.

I've been dealing with this. There's a known defect, Defect 832802. Affecting all of the Microsoft domain email servers including Hotmail, MSN, Live and Outlook (personal).

This defect only has a U4 priority right now, which can be WEEKS to resolution. I'm at about 10 business days not being able to reach customers and we're having to make great efforts to diffuse customer service nightmares and delays as a result of this. As an Ecommerce business it's been horrible.  I hope you and any others affected report and lean on your NS Account Rep to escalate.
