We are currently investigating an issue affecting outbound email delivery for some mail accounts hosted on the White Light mail server.
Some customers may experience delayed emails, bounce-back messages, or messages not being delivered after sending. This may affect emails sent from desktop mail software, mobile devices, webmail, and third-party systems such as accounting or CRM platforms where they use the hosted mailbox to send.
The issue appears to relate to the external outbound mail filtering/relay service used by the server. We have escalated this urgently with our server infrastructure provider, who has confirmed that the incident is still ongoing and is also affecting other services that use the same filtering platform.
At this stage, inbound email may still be working for many users, but outbound delivery is unreliable for affected accounts.
What we are doing
We are working with our infrastructure provider to restore reliable outbound mail as quickly as possible. A temporary bypass of the affected outbound filtering system is being reviewed/implemented so that mail can flow directly from the server while the external filtering issue is resolved.
What customers should do
If you receive a bounce-back message, the email has likely not been delivered and may need to be resent once the issue has been resolved.
If you sent important emails, invoices, quotes, reports, or customer documents during the affected period, we recommend checking for bounce-back messages and resending any critical emails once we confirm outbound mail is stable again.
Please avoid repeatedly resending the same failed emails until the issue is confirmed as resolved, as they may continue to bounce.
We apologise for the disruption this is causing. We appreciate how important email is to your business and are treating this as an urgent service issue.
Further updates will be posted here as soon as we have more information.
