Smartsheet SPF failure since November, coming from Sendgrid
We've been getting problems receiving emails from SmartSheet since start of November – failing SPF checks as the IP of Sendgrid is not within their spf record. Looks like emails prior to November were being sent out via Mimecast which is in the SPF record.
For security reasons we’re not adding the domains into the allow list.
Is there a chance someone from Sendgrid can review their SPF record?
I’ve tried to contact support multiple times about this but they’re stuck reading from a script and are just focusing on advising me to add the domains to the allow list rather than fixing the root cause.
Emails are coming from ‘[email protected]’
