clum1 -> CDONTS and Exchange (18.Oct.2006 5:08:59 AM)
I've got an intranet where I use CDONTS to send messages back and forth. A significant number are not being delivered though correctly addressed. It seems they are leaving the organisation from the intranet server then being caught in our (externally hosted by F-PROT) spam filters. My question; is there a way to set my intranet server to post CDONTS mail directly to my Exchange server, thus bypassing the spam trap? Calum

You could if you have an internal DNS server, then you can set up an MX record pointing to your incoming mail server and thus will avoid be sent externally...

Assuming that the CDONTS application is based around ASP you could configure an IIS SMTP server which has a smarthost set either as your Exchange servers's virtual SMTP server -or- just use DNS on the IIS server, but this is only if the CDONTS application is IIS based. A

Hi guys, thanks for getting back to me; it's only now I can devote any time to this! The problem is still happening and I am still stumped. The CDONTs app is based on IIS (4 or whatever it is on ancieNT) and I would have the ability to setup either a DNS server or IIS SMTP server but I don't know where to start. Could anyone point me in the right direction please? Does the DNS server have to be on the same box? I have all the bits, just need the brains to help me stick it all together... cheers Calum

You can set up DNS service on any server incl it can be either a Unix box or Windows NT, 2000 or 2003, it doesn't matter. But the TCP/IP properties of the Exchange or SMTP server needs to point to that server. If you need internet resolution then you need to configure your ISP's DNS IP addresses on the Forwarders on DNS server. For NT4, you can install DNS via Network properties and add it on the Services tab. For 2000/2003 you can add it via Add/Remove Windows Components or use the 'Configure my server' admin tool.

Thanks again for getting back to me; I've setup a 2k3 box as a DNS server and have both my IIS intranet server and Exchange server pointing to it as their DNS server. This seems to work - ie. they both resolve internet addresses fine though nslookup returns an error saying it can't find server name - No-existant domain. On the DNS box, I have set up an MX record (in the forward lookup zones) but it does not seem seem to work. I am not sure if I am giving it the correct info; Host or child domain: same as parent folder FQDN: <NT Domain name> FQDN of mail server: <ExchangeServerName>.<NT Domain name> Mail server priority: 10 I tried setting the ExchangeServerName to its IP address, but this failed to even send the message. Is there something else I'm missing? Calum

You need a NS (Name server) and a A (Host record) for the DNS server. It also helps to have a Reverse Lookup Zone which resolves IP addresses back to hostnames. Also, run IPCONFIG /all and check that the FQDN is shown (Host name + domain), otherwise you need to specify the FQDN in the Network (or computer) properties.

clum1 -> RE: CDONTS and Exchange (21.Dec.2006 8:07:33 AM)
thanks; I have the NS and the A (Host Record) both pointing at the DNS server itself, ie. DNS server is called BES1, Name Server is BES1. and Host(A) is BES1's IP address. Running IPCONFIG /ALL gives the hostname as BES; should I change this in System Properties / Computer Name to DomainName.BES1? Thanks again for your help; this is all new to me! Calum

pjhutch -> RE: CDONTS and Exchange (22.Dec.2006 6:11:31 AM)
No, it should be BES1.domain e.g. BES1.mycompany.com

clum1 -> RE: CDONTS and Exchange (8.Jan.2007 4:49:22 AM)
Hi there; still haven't got this resolved... If I try and change the computer name in the System Properties tab it won't allow me to change it to include periods - e.g. BES1.mycompany.com How do I get round this? Also, my NT domain name is different from my email domain name - which would I use? thanks again, Calum

pjhutch -> RE: CDONTS and Exchange (8.Jan.2007 11:56:00 AM)
No, what you do is click on 'More...' then for the Primary DNS suffix add the mycompany.com there.

clum1 -> RE: CDONTS and Exchange (9.Jan.2007 3:07:39 AM)
Thanks again; I think I'm getting lost here, though I've managed to get that sorted out now. If I run ipconfig /all I get: Host name: . . . . . .bes1 Primary DNS suffix: . . . . . .emaildomain.com Node type: . . . . . Hybrid IP Routing enabled: . . . . No WINS Proxy Enabled: . . . . .No DNS Suffix Search List: . . . . emaildomain.com Just to clarify, should it be bes1.NTdomain or bes1.emaildomain.com? I think I may have lost sight of the original problem - will getting this up and running ensure that any mails generated by the IIS server for emaildomain.com stay internally or will I need to rconfigure it too? thanks again Calum

pjhutch -> RE: CDONTS and Exchange (9.Jan.2007 4:11:12 AM)
The DNS suffix should match the domain in your dns server.

clum1 -> RE: CDONTS and Exchange (9.Jan.2007 4:38:54 AM)
Many thanks - it now seems to be working. What I thought was a further error actually turned out to be the proof - sending an email from my IIS development PC was routing out on the internet whereas live server ones weren't. I have of course left the DNS settings as default on the dev PC, thus the "error". So the live one definitely works! Thanks again for your help, Calum
