This is now resolved
I can’t see that this is currently resolved, we are still reviewing this. with Postmark
We are seeing a current outage at Postmark our SMTP relay provider for messages going from select clients PBX’s for voicemails and some other communications such as scan2email and website email enquiries.
We will update our service status as soon as we receive an update however a live update of the issue is available here:-

In the interim we are fairly sure that any website/scanner communications will not be sent however we are unsure if messages left on voicemails will be queued by the phone system or lost until the server comes back online.
