Web hosting customers, and e-mail customers with spiralemail.com and sierraemail.com addresses, are reporting problems with delivery of outbound messages. Many messages are failing to be delivered, with a delivery report being sent back to the sender indicating that they were rejected due to spam violations.
This is due to the hosting server being placed on spam blacklists after a series of accounts were compromised (in unrelated incidents) and malicious messages sent out from each of them. The accounts have been re-secured, but the process of getting removed from the blacklists is taking longer than expected due to multiple violations within quick succession.
We are actively working on restoring full operability, but do not have an ETR at this time.
Edit: Deliverability was restored Sunday evening, July 3. If you are still having problems please contact our technical support at (530) 478-9822, Ext. 1.
