E-mail & Website Downtime during DNS modification phase

Understanding why some Emails and content might get blocked by Trend, and how we manage your whitelist

There will be a minimum downtime period for all domain related services during the setup of your Trend Email Security. The outage can last anywhere between 1 and 7 hours, and in some rare cases with less reputable domain hosts, up to 48 hours. Most good domain hosts have faster propagation times, resulting in a faster turnaround.

Layer 3 staff can generally indicate the timeframe once the host’s details have been provided.

During the initial ‘learning’ period for Trend Email Security, there’s a good chance that some legitimate content will be unintentionally blocked and require manual whitelisting. While there’s a multitude of reasons for why a particular Email or Domain might be flagged as unsafe or suspicious, Layer 3 suggest contacting our support team if you suspect you are not receiving emails.

Please contact us on and include the full email address with a rough timeframe of when that email was meant to be received if you suspect this is happening to you.
