Opalstack - Delays in mail forwarding to Google – Incident details

Google is once again rate-limiting messages forwarded from our MX servers. We're working to resolve this and expect the backlog to be cleared over the next several hours.

As a temporary workaround, customers can route an Opalstack mailbox to their forwarding email address and then use that mailbox as a POP3 account in their Gmail settings.

We will update this post when the backlog of forwarded messages is cleared.
