Hi:
The KMS is running fine except that webmail is failing to the outside email addresses. I have already configured the HTTP service to use port 8383. To access webmail, I go to http://www.Modomain.com:8383 and am able to see received Emails and can also send to xyz<_at_>mydomain.com but not to xyz<_at_>yahoo.com.

Looking into Kerio's Mail Queue, I can see "DNS Lookup Failure 4.4.3. Also, in "Mail" section of KMS, I see that "Sender-Host" is my own IP Address (the home computer's) and not the webserver's IP address.

I am positive that there was no issue before but now it does not work (I mean, the webmail part). The only change I can think of is that now I have a DNS Server running to allow a few websites to run on my server. Is that what could be causing the error?

please help!!

Having a few websites running and running a DNS Service are two completely seperate things... You don't need a (your own) DNS Service for websites to run properly. You just need your websites domains to be known in the public Internet DNS (which most probably does not include your own DNS Service).

But you're right: your own DNS is causing the problem. Try resolving the domain of some mails that won't go through manually on the mailserver itself (for example, ping them from a prompt). You'll see your system is not capable of resolving the domains to their IP addresses, so it doens't know where to send these outbound emails.

Solve your DNS problem (this is seperate from KMS) and your problems are solved as well.

But from your post I make up you do not know a lot about DNS, so maybe you just have to call in some expert help...

You are right: I don't know much about DNS. It was installed on the server by someone else who wants to transfer his own websites to the new server--the old server will be no more and it will transfer its own DNS records to the new server.

I don't know what kind of bearing running the DNS server may have on KMS. Any? I mean, why KMS was able to deliver mail to <_at_>yahoo.com before using webmail and not now?


Anyway, using Remote Desktop, when I ping mail.healingtouchforyou.com it does not work--cannot find host.

But, from my home computer, it pings fine.

Thanks.

There is no need at all to run a DNS service if the purpose is just to run a website. DNS services for websites are not run locally, but by a domain provider. So DNS records do not have to be 'transferred' to the webserver itself, as you say.

But obviously this DNS service is messing up the working of DNS on the mail server. It is essential that domain names can be resolved to IP addresses on the system on which KMS runs. As long as you can't resolve names to IP addresses (which is basicly what DNS is for) you won't be able to send out mail.

So, as long as pinging some address does not return an IP address (as a way of testing) you're in trouble.

If I were you I would ask, no, tell the person who messed it up to fix it...
