Identified
We identified the issue causing the email delivery delays: Microsoft is limiting the number of connections from our mailserver, mail01.smartt.com.

While we wait on Microsoft to resolve the issue on their end, we implemented workarounds to decrease the delivery delays. Many clients should no longer experience a delay when sending new messages to email addresses hosted by Microsoft. Over half of the messages that were queued at 12:00 PST have been delivered.

We continue to monitor the issue and adjust our workarounds to minimize delivery delays. We will provide another update by 19:00 PST.

Investigating
We are investigating an issue causing email delivery delays from our primary email server, mail01.smartt.com, to recipients who use Microsoft's email services. This issue also affects clients who forward their email hosted with Smartt to an email address hosted by Microsoft.

We contacted Microsoft's support team to get assistance on this issue from their end while we investigate it on ours. We will provide an update by 18:00 PST.
