NC027: Issue with outgoing mail to MessageLabs/Symantec

6 April 2017 13:36:18 +0000

For several hours now we have been noticing that emails sent to domains hosted by Symantec on mail exchangers running their MessageLabs service (or the service formerly known as MessageLabs) have been stalled on our mail server (NC027) with errors such as the following:

(delivery temporarily suspended: lost connection with cluster6.us.messagelabs.com[216.82.242.46] while sending message body)

Particularly, messages with multiple recipients seem to be stalling like this, while other outbound emails to other domains not hosted by Symantec seem to be going out with no problem. Some messages appear to be going through over time, but not all.

Destination domains that seem to be affected by this include the following:

  • barrick.com (Barrick Gold Corporation)
  • sc.com (Standard Chartered)

We’re continuing to monitor this situation, but at this point there doesn’t seem to be anything that we have the power to do.
