Hi All,
We have Active Directory Domain Name is mycompany.gr (wrong decision)
and also we have a site hosted externally as www.mycompany.gr
and finally pop3 to get email from the provider www.mycompany.gr

Because mycompany.gr is Act Dir Domain name and web site is not possible to
get emails

Is there any solution ?
Thanks

Although you are correct this is not a recommend way to go, the current
company I work for has such a name space and things work just fine. Do you
have your mx records defined properly?

You say it doesn't work what doesn't work?

Also this really has nothing to do with AD and is an Exchange issue, so I
have copied the Exchange Newsgroups in on the discussion. Since I believe
this is really where this thread belongs.

Receving mail for a domain is based on having mx record for that
domain and configuring your recipient policy. To receive mails for
domains that you are authoratative for use the article below.

The OP didn't mention Exchange - he POPs email from his ISP. Why do you
think he has an Exchange issue?

Hi Evan,
First of all the FQDN of your AD doesn't have to be the same as your public
domain name (and shouldn't be setup like that most of the times). If your
Internal FQDN is the same as the public domain you've to configure a
split-brain DNS solution. Because you're saying that you've POP3 clients
I'll assume that your mail server is hosted outside of your DMZ/Network, for
example is hosted in your ISP.

The problem is the following, when your clients are trying to solve the
pop.yourdomainname.gr or the smtp.yourdomainname.gr, they ask your DNS
server where to find the records for pop.yourdomainname.gr and
smtp.yourdomainname.gr, since your DNS server is autoritative for the
yourdomainname.gr and doesn't have any pop or smtp record, your clients fail
to solve the address for those records.
Solution:
1- Instead of using pop.yourdomainname.gr and smtp.yourdomainname.gr, you
can use in the clients mail configuration the ipaddress rather than the pop
and smtp records.
2- Or you can create the records for smtp and pop in your internal dns with
the ip of the mail server that is responsible for your mail.

How do you know the public address of your mail server, well, you can use
nslookup to search the public address (carefull, if the machine where you're
performing those tests is using your internal DNS you won't get the public
address, use another machine to figureout that), you could ask for your ISP
(assuming that you're using your ISP as mail hosting).

Another tihing, some people talk about MX records, well, in fact MX records
are only used by people that send you mail, in sum, when someone sends you
mail the smtp relay needs to find the MX record for your domain name in
order to delivery it. Let's say that people where saying that they couldn't
send you mail, in this case the lack of MX record (created in a public DNS)
could be the problem.

I hope that the information above helps you.
Have a Nice day.

And if his ISP is using Exchange? You also don't know that. The point is
that the same principle is applied, and from client prespective they all
work equally.

You've already posted the right answer so you KNOW it isn't an Exchange
problem. It doesn't matter what mailserver the ISP is using.

Exchange.

Thank you

Yes we do not have any internal email server. We are connecting to our ISP
and we use www.mycompany.gr as pop3 and smtp in our mail.accounts
So I will try to create into internal dns records for pop3 and smtp

Thanks again
Evan Kosteroglou
