Maintenance Window:-
Monday 31st March 3.00pm-6.00pm.

Service Affected:-
Email.

Duration of expected customer impact:-
No negative customer impact is expected.

Detailed description of work to be performed:-
We will be migrating the final batch of customers' accounts to our Postini anti-spam platform in preparation of a number of enhancements we will be making later this week to the Manage My Mail spam controls on the portal. This batch consists of around 3,500 Force 9 customers.

Expected customer impact:-
Once these customers are migrated, the only change should be a visible reduction in the volume of junk email that gets delivered. It can take up to 7 days after migration before the full benefits of the new system are seen:-

Other Notes:-
When a customer is moved to the Postini anti-spam platform their mail records are changed to point to Postini instead of our mail servers. As this is a DNS change it can take 24-48 hours before the changes have fully propagated across the rest of the Internet.

One trick used by spammers involves them sending email directly to the old mail servers. This bypasses the Postini checking so we need to block attempts to do this after migrating each customer. This block is applied 7 days after migration at which point customers may notice a further improvement in the performance of the spam filter.

Please accept our apologies for the late posting of this announcement.
