Exchange 2000 inbound/outbound smtp mail not working

[lfoldesi]

Hello,

I have a small business server 2000 machine running with exchange 2000 installed. I can not send or recieve internet mail. I will describe my configuration first.

1 small business 2000 server with exchange running.
1 NIC in server.
1 dsl router
1 registered domain name
1 static IP assigned to router
DHCP running at router
2 client PCs connected to routers 4 port switch
I disabled W2k servers DHCP services
Configured w2k DNS to use DNS servers from ISP
Exchange server has internal IP (192.168.x.x)
port 25 on router set to forward to IP of exchange server.

Obviously this is incorrect because it does not work. What am i missing. Do I need another public IP for the exchange server and install a second NIC. Or...are my dns setting incorrect.
My Exchange reference manual states that if my exchange server is using the default NIC with a internal IP I must install second NIC and get another public IP.

Help I'm somewhat confused and the GREAT MICROSFT will not give me support because this is an eval version of small business server 2000.

You already have the answer right in front of you....
Add the puplic IP and register your Mail server on a DNS server i.e. mail.whatever.com, the reason for this is that other mailservers can get to your mail server.

Hope this helps

What is your domain name? IP for Router?
Point E2K to W2K DNS and setup forwarders on DNS server out to ISP. If you point E2K to ISP for DNS your going to have more issues than I care to even talk about. Just don't do it. W2K needs the SRV records ALL the time so never have it even think it can look at another DNS. Granted if the DNS is on Bind 8.2 or better it will be ok but I still wouldn't want to support it.

FWIW - If you can't send it is almost always DNS. If you can't recieve it is almost always MX record. If you setup a SMTP connector remove it and use what was installed with E2K.

I can send outbound e-mail but can not receive inbound e-mail. I have dns in w2k disabled and am ponting to external dns.

If you have a MX record pointing to your server you should get mail. If you give me your domain (user@microsoft.com) name I can tell you what is wrong. Dan

I am going to be setting up our company server in the same manner.

Same configuration setting.

Am I to understand that I need to register two domain names?
i.e.

http://www.mycompany.com

& mail.mycompany.com.
or do I just setup the one IP and then configure Win2K to foward this type of traffic to an internal IP(E2K Serv.)?

 

[Xybertron]

You register mycompany.com and thats it. You then point MX record to daserver.mycompany.com and put an IP. As long as the IP is right you could call the server goofy if you wanted. Dan

We just upgraded from exchange 5.5 to 2000. We are using outlook and can recieve email but cannot send email. Any ideas??

compujer - Can't send e-mail is because yo can't resolve MX or have some sort of block on port 25 going out. Dan
