Hi everyone,

My problem: I have just installed exchange 2010 successfully but I'm only able to send email withn my domain (sdserver1.com). Could anyone give me help to resovle this problem. Also I'm new to exchange.

My setup is, I have one computer running windows server 2008R2. On this computer I have three virtual OS (Server 2008R2) running on hyper V which are:
1. Domian Controller
2. Domain Controller and Exchnage 2010
3. Windows 7.

The computer is behind a router DLink DIR-655.

Ports that are beeing forward to the Exchnage 2010 server are:
HTTP - 80
HTTPS - 443
SMTP - 25
POP - 110
IMAP - 143
IMAP SECURE - 993.

From here you can see my dns recored (I think here is the problem) - http://www.who.is/dns/sdserver1.com/

This is the link to the Outlook Web App. https://mail2.sdserver1.com/owa

Thanks for any type of given.

Update:

this is what i'm receiving now when i try to send an e-mail.


tungsten1.melitacable.com gave this error:
<c62-19.i05-16.onvol.net[88.203.62.19]>: Client host rejected: Your message was rejected due to spam filtering. Please see http://www.sophos.com/security/ip-lookup?ip=88.203.62.19
Your message wasn't delivered due to a permission or security issue. It may have been rejected by a moderator, the address may only accept e-mail from certain senders, or another restriction may be preventing delivery.

I think, I need to contact my ISP becasue I'm being blocked?
Any other theory are welcome.

My current public ip is dynamic, although it rarely change. Can that be the problem that email will be rejected from other servers?

Hi ,
 
Your ip 88.203.62.19  is listed on spam database , It appears to be infected with a spam sending trojan or proxy.

Please contact your ISP to  remove your ip address form the spam database, and also check your router setting as well your internal network, you can also check block ip list using http://www.mxtoolbox.com/SuperTool.aspx?action=mx%3a216.69.185.28

And also check your respective ports are open related to mail services.

Let me know for any query.

Regards,
Tejash Joshi
