hMailServer forum

Hi,

Let me first say that hMailServer is a great program!!
But i get an strange error on one of my computer. If i run it and i try to test the smtp then i receive this debug output in the log:

"DEBUG" 2060 "2004-07-26 13:15:17.107" "SMTPDeliverer::_RelayMessage()"

If i try it on another computer in my network where i also have hMailServer installed then i get:

I also put "ComputerName" in the hMailServer.ini but still no luck.

enable the smtp logging let's have a look at what that says. also what type of setup do you have? any proxy's?

I don't have any proxies...what do you mean by smtp log? You mean smtp log of hmailserver or do you mean smtp log of my exchange server where i try to email?

I think it's an internal problem because he cannot even resolve my domain.

open hmailserver admin - go to logging and enable smtp logging.

it's most likely not a software problem so let's have a look at that first.

what other tests have you done that prove that this is an internal problem?
so you're trying to send an email to your own exchange server that is on your network?

what about dns? do you have some kind of network dns server? you see, it could be a hundred and one different things.. send over a copy of that smtp log from hmailserver and we'll have a look at it.

actually - it might also be helpful to have a look at the smtp conversation on the exchange side as well.. but that's secondary to the hmailserver log.

delete the existing one, attempt to send your message from the computer that it doesn't work from and then copy and paste that here.. you'll find the logs under c://program files/hmailserver/logs

Yes my dns server is also my exchange server.

that was in the last few lines... try doing this with another dns server and see if you get the same results.. i doubt that you will. I dont' know a whole lot about dns servers - but maybe you can check to see if united-brands.nl is listed in the dns server that you have hmailserver pointing to.

this is not an application problem - this is a dns resolving problem. let us know what you dig up.

This _could_ be a application problem but Polarunion is right that it doesn't seem to do so. hMailServer does a simple MX lookup but can't find any server. :-\

What OS are you using (Windows version)
What's the IP of your DNS server? (I can connect to it and see if I get the same error)
