Email notifications seem significantly delayed. What's happening? Is it on the xMatters side or ours?
All versions of xMatters On-Demand; all mail server and client versions
To resolve this issue, we'll need to collect a few samples of the messages that were slow to be delivered. We need the original messages so we can check the email headers - for tips on how to review e-mail headers, this site contains instructions on how to do just that.
If the email messages are in msg format and you use a Mac, you have two options:
- Use another app like MailReader; or,
- Log into Office 365 and create a draft uploading the samples. Once the draft is saved you will be able to see the samples in the online version of Outlook under the Drafts folder.
Copy the email headers (also known as raw source or message details) from one of the samples.
Check for any columns that contain the word "Delay" to determine which hop experienced the delay. In the following example we can see on the third row under Hop Delay that it was over 1 day and 1 hour. That indicates the issue was between the source and destination servers where see the longest hop delays and in that case you need to contact that provider or the mail server's administrator team who probably will need to check their logs to determine the root cause.
An external hop in the SMTP delivery chain was delayed (outside of xMatters and the local mail server) and that hop needs to be contacted and alerted about the delay. This can be anything from antivirus scanning or anti-spam or email security solutions.
