Email not delivered to specific distribution group

Our Trend AV server sends out an email alert when a virus is detected. It's sent to 3 groups, 1st level support, 2nd level support, 3rd level support.

1st and 3rd level receive the alert. 2nd level do not. Why?

look for the obvious first - if the other two groups are recieving it, its likely your SMTP settings and exchange portion is fine.
The the email address for the 2nd dist group specified correctly ? Do you have any blocks on the 2nd DL ?

What does message tracking show?

Thanks for the replies.

The email address is definately correct for the distribution lists.

Message tracking shows it being delivered to Exchange Server A, and the people that are on that server, then to Exchange server B, and the people that are on that server. It also shows an NDR being generated, but no details for what. The people in the DL that do not receive the message, are on the same server as me, I'm in one of the different DL's, and I receive it.

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Server location has nothing to do with DLs.
Although do check the expansion server on the DL is valid.

What kind of SMTP settings could be affecting this? That's the only thing left that I can see, as it's delivered to Exchange Server A, then from there to Exchange Server B. When it hits A, an NDR is generation in the message tracking.

HayesJupeCommented:
can you pst the NDR - this will give us the best indication as to the cause of the error.

How do I get the details of the NDR, nothing is shown in the message tracking?

HayesJupeCommented:
send the DL a message from your account.... you'll get an NDR back... :-)
<unless your telling us that the message disappears into the ether an no NDR is sent... but you've told us above you can see the NDR being generated in the message tracking logs>

OK here's an update.

I changed it to my email address, and then everyone receives the message just fine.

The original FROM email address was one that does not actually exist.

How would that stop it being delivered to just one DL?

Check the delivery settings on the list to see if there are any restrictions on there.

Yes it was a restriction on the DL. Thanks
