Our 2nd attempt to upgrade to our new SpamTitan 6.0 server has gone smoothly. There was no disruption to incoming mail flow.
It is possible that customers will receive duplicate Spam Quarantine Report emails tomorrow as the old server is still running alongside the new one and any mail that has already been quarantined prior to the upgrade will remain on the old server until released or automatically purged.
Update 2013-12-12 22:28 GMT
The migration is complete and all Hosted Email services are now back up and running on the new SSD RAID array.
There was one minor issue that arose during the migration: the time on the new server was running fast by just over 2 hours, and the clock did not sync immediately at startup time, so a few emails were delivered with timestamps in the future. Sorry about that.

We’ll be adding additional storage space to our mail.anu.net Hosted Email server tonight at approx. 22:00 GMT
We are also taking the opportunity to migrate all the mail storage from 7200RPM SATA disks to new SSD drives, bringing big performance increases and lower energy usage.
A short interruption to service is unavoidable but we’ll do our best to keep the downtime to a minimum. We’ll update this post to confirm when we’re done. Apologies in advance for any inconvenience caused.
It came to our attention this morning that email from Gmail accounts was not getting through to our Hosted Email customers. After running every test we could think of we discovered Gmail’s servers were failing TLS negotiation with SpamTitan, and not failing back to unencrypted SMTP. We have temporarily disabled TLS support on our SpamTitan server and mail is now coming through again. Any messages sent from Gmail since we restored SpamTitan yesterday morning will be delivered to your inboxes shortly.
This issue may also have affected some other email providers, though Gmail is the only major provider we are aware of that was behaving this way.
