Exchange 2010 -  Delay in email received

Posted on 2016-10-03
Medium Priority
Last Modified: 2016-10-17
I'm experiencing delays from email coming from a specific domain.  I don't believe the issue lies with our server, but sense the delay is from two different domains, I wondered whether there was something in our server that was causing this delay. Below is some of the header information for the delayed emails:

Take the header info you have and run it with a header analyzer from MxToolbox.com or exrca.com.  That might suggest to you where the delay might be.

It seems the delay happens between mout.perfora.net and our email server. Is there a way to figure out what is causing this delay?

Will you post a screenshot of the header analyzer output?

Block out (redact) anything you don't want us to see.  I'd like to get a holistic view of the mail flow from sender to recipient.
Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

That's a brutal delay.

I was assuming there would be more hops before it was delivered.  Help me understand this specific mail flow from sender to recipient.

What are ACCOUNTINGSD, mrelay.perfora.net, what is mount.perfora.net, and mail.ndapc.com?

ACCOUNTINGSD is the original computer sending the email

They use an email service know as 1 & 1  as their mail provider.  mrelay.perfora.net is this providers server.

mail.ndapc.com is our server. We host our own exchange server.

This is the only domain we are having delay problems with,

Are the delays predictable and consistent from that specific email domain?  

If so, and no issues with other senders, I would contact that specific email provider.
