User stopped receiving emails or emails marked as spam once the "From" address is changed to company domain in ServiceNow instanceIssue Users stopped receiving emails from ServiceNow instance or Emails are marked as SPAM once the "From" address is changed/spoofed to company domain (From: "company@mydomain.com") in either email account or Notification "From" field. ResolutionChanging the "From" email address to your company domain (e.g. company@mydomain.com) might affect the outbound email delivery. If your company prevents email from being delivered from unknown IP addresses, you might stop receiving emails or email might be marked as SPAM. Once you spoof the "From" email address in the ServiceNow instance the email will be going out as "From : company@mydomain.com". If email stopped or marked as SPAM after spoofing "From" address then you need to include the ServiceNow SPF record to your domain's SPF so that the emails will not be marked as SPAM by the receiving mail server.(since the from address is spoofed). Refer KB0535456 to enabling email delivery using SPF records to allow SN mail servers. Refer KB0823655 on how to change/spoof the "From" email address to your company domain.
