We have identified an issue where some customers may receive bounce-back messages when sending emails to Outlook, Hotmail, or Live.com email addresses. This is due to missing or incomplete email authentication records (SPF, DKIM, and/or DMARC). Microsoft has recently strengthened its email security requirements and may reject messages from domains that do not have valid email authentication records configured, even if email delivery was working previously. To resolve this issue, please ensure your domain has valid SPF, DKIM, and DMARC records configured. You can manage your DNS records by following this guide: https://support.digitalpacific.com.au/en/knowledgebase/article/how-do-i-add-spf-and-dkim-records SPF and DKIM are already valid; you can add the following DMARC record to your DNS zone: Host: _dmarc.yourdomain.com (Replace yourdomain.com with your actual domain name) Value: v=DMARC1; p=quarantine; sp=none; rf=afrf; pct=100; ri=86400; We understand the importance of reliable email delivery and appreciate your patience. Please continue to monitor this page for further updates.
