    [Host Unreachable] Exchange 5.5 Internet mail service

    GP8, Thank you for that post. I'll look into trying to set up a relay in a DMZ, but the confusing part to me is that we just don't have anything w/ an underscore in it, but maybe it will still work. I appreciate the diagram and links as well. Thanks again for all your help..

    [Host Unreachable] Exchange 5.5 Internet mail service

    Ok, What gives here?.. I've received email notices of 3 updated postings in this thread yesterday evening, yet they all seem to be gone this morning.. one from MarkAskew, one from kilfarsnar, and one from msdIT. Not one of them are showing up. Has the moderator cut all 3 postings? Moderator...

    [Host Unreachable] Exchange 5.5 Internet mail service

    GP8.. The use of an underscore in your case may either be the problem, or be contributing to the problem in your case. There's still another issue though regarding this though because several of us experiencing this problem do not have underscores in our configuration. Good luck, and let us...

    [Host Unreachable] Exchange 5.5 Internet mail service

    I agree w/ you re: not blaming M$ for shooting in the dark.. We've all been doing that for months.. ;) Sooner or later they'll end up having to escalate it to higher levels as long as kilfarsnar keeps bugging them about it, which, since I'm sure they've already charged him for the incident, he...

    [Host Unreachable] Exchange 5.5 Internet mail service

    I don't know.. Not willing to rule anything out yet, but it kind of looks like M$ was shooting in the dark here a bit.. The first update I could see as a maybe, don't really see the 2nd update applying to this issue, but please let us know..

    Kilfarsnar: The fact that you did a new install from scratch on different hardware with everything fresh except the DB's, takes me back to something breaking down in the receiving domains interpreting of some piece of information. Something different about the receiving domain's configuration...

    [Host Unreachable] Exchange 5.5 Internet mail service

    I can pretty much rule out the user config side.. Already went down that road in the very beginning.. At least in my case.. tried sending to several of the problem domains from multiple clients with the same results on each client. Messages are getting from the client to the IMS queue, but...

    [Host Unreachable] Exchange 5.5 Internet mail service

    No help there for me.. Tried doing the same but it didn't make a difference. Sent a test message to a couple of the domains we have problems with and it's still sitting in the queue with a [Host Unreachable] error.. ;( Thanks for the info though.. Was definitely worth a try.. Tony

    [Host Unreachable] Exchange 5.5 Internet mail service

    We're running Norton v2.14, and Veritas v.8.5, but Veritas is actually running on a different server and backing up the exchange server remotely so I can't see where that would effect it. Also, attachments are not a pattern with us. It makes no difference whether there's an attachment or not.

    Any more information re: this thread? We've been having the same problem for months now and like the rest, I've pretty much exhausted my ideas by going through the same processes.. ;(
