Things to check if messages are queued
Once you have located the email under Inbound Scrubbing or Outbound Scrubbing souble click on the message in the search results which will give you more details. If there is a generic queuing message then there may be an issue with your firewall or mail server which you may wish to investigate or in the case of an outbound message there maybe an issue with the recipients server.
You can contact the SMX Service Desk to see if we can reach your mail relay host from our servers.
Once you investigate and resolve the issue the emails should start flowing again. We try every 15 minutes to send the emails through.If you see a message like “Insufficient system resources” then the recipients server hard drive maybe full or the server maybe out of memory.
Once you investigate and resolve the memory or hard drive issue the emails should start flowing again. We try every 15 minutes to send emails through.
