My workflow emails stopped working after switching SMTP to Microsoft/Office365. What should I do?
If workflow emails stopped working after switching your SMTP server to Microsoft/Office365, it may be due to SPF restrictions. Your domain needs to authorize the sending IPs used by Vtiger’s mail server (eu1.vtigermail.com). To fix this, you will need the exact IP ranges or SPF include mechanism. Please contact [email protected] to get the required details so your IT team can update your SPF record and restore workflow email functionality.
