One more note, in case it wasn’t made clear earlier. All new email to migrating and migrated domains is being delivered to your accounts on the new server, unless it is sent by someone using the old server. This means that email from contacts not hosted with NinerNet will arrive in your account on the new server. However, email from clients still hosted on the old server — and from people on migrating/migrated domains who are still using old email settings to send email — is being delivered to the accounts on the old server. Avoiding this overlap is why we had hoped to complete this migration on the weekend, but it will be rectified by the sweep we will make at the end of the day today.
As always, we’re here to help if any of this is confusing. Please contact support if you have questions.
