Greetings,

long story short, I have about 200 emails stuck in queue since yesterday afternoon. Yesterday evening I noticed and rebooted both exchange servers. After, emails starting flowing properly. However, about 200 are stuck in queue with error "451 4.4.0 primary target 554 no smtp service...". We relay through a smart host.

Any help getting these released is appreciated.

See if this helps

Go into the EMC,
- select Server Configuration
- in the window to the right, right-click the correct server, select properties
- select External DNS Lookup Tab - make sure "Use network card DNS settings" in the drop down select the proper network adapter
- press apply, ok...
- restart transport service

thanks TG-TIS. I looked there and 'all IPv4' was selected. I did not change it yet since email is flowing properly now and I don't want to mess with email flow after yesterday's mess. That said, I do have a DAG set up so when I click the dropdown, I see my VMware adapter and the MS cluster adapter. I would think to choose the VMware adapter but I'm not what this would do to mail flow.

thanks again

Yes, if your running VM, then that's the adaptor I would select.

Can you telnet to the smart host on port 25 from the Exchange server?
If so, restart the transport service on the server, that will usually kick things back in to life.
If you are using a commercial smart host service it could be that one of their cluster is down, but Exchange has a habit of caching DNS entries.

Simon.

I ended up restarting both servers. We had a good connection to the smart host since all email except the 200 in queue were moving correctly. Mail stayed in queue and then expired.
