Just for the moment, take the Edge server out of the equation. Can the internal HT send email directly to the Internet?
If so, I'd blame this on your subscription. How did you set that up? Regards, Michael B.

Hopefully, you can help me figure this out, because I'm a noob to 2010. Lab environment: 2 MB servers, in a DAG. 2 HT/CS servers, with WNLB for the CS role. 1 TMG in the DMZ, to handle client access security 1 Edge server in the DMZ, to handle mail flow Internal e-mail works flawlessly. At the moment, incoming e-mail from the outside world works fine. Outgoing to the internet is not working. I'm getting a "#550 5.7.1 Unable to relay ##". So the message is going from my internal HT server to the edge server, then it's getting kicked back with that error. Looking at my Send connector (EdgeSync - Default-First-Site-Name to Internet) I see the following settings: Address Space Tab: smtp * 1 (Type - Address - Cost) Network Tab: Route mail through the following smart hosts: IP of the Edge Server Smart host authentication - None Source Server: Name of edge server My initial thought was the Smart host authentication, but changing that to Exchange Server authentication didn't change the error message I'm getting. Any tips/advice/push in the right direction would be immensely appreciated. >>> "Michael B.

That being said, as long as you only have one default gateway, it's not a big deal regardless. Regards, Michael B.

We have a DMZ setup, we have the Edge box installed in this zone. Currently, it has one NIC, with a public IP on it. My question: Is the box supposed to actually sit completely in the DMZ, or is it supposed to have a second NIC, with an internal IP, therefore "straddling" the firewall/DMZ? I have not been able to find any info on this issue. Any pointers to further/better info would be appreciated also. I've already looked at TechNet, and there doesn't seem to be any reference to actual network configuration. --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist
