Hi Everyone, I set exchange couple of days ago at home, I am able to send and receive emails between users using the same domain. Now, the problem, and I think is that my ISP Bell Sympatico blocks port 25 and many others. To be able to send emails to external/outsite domains, I has to configure "Route mail through the following smart host, and added my ISP's SMTP server". But here I am not quite sure, why emails coming to me, are not going through...Do I have to do something similar to receive emails ? It has to be done on my ISP's end or me ? I don't get any errors when sending email, just nothing happens, email disappear. My connection is Fine, DNS is fine also... Can please someone help me with that or give me a workaround ? I am new to Exchange, so please be nice with me :)

You need to have MX record for receving emails. If you could tell us your domain we can check externally if there is MX record avaible for that domain.Jasjit Singh Dhindsa | ITIL v3 | IASA Foundation Certified | MCITP: EMA 2010/2007 | MCTS: MES 2010/2007, OCS 2007 | MCSA: M+S | MCSE: M+S

Jasjit, Sure, my domain is rogerakl.com I have MX records, but you can double for me if you can... Thank you!!

The MX Record does exist and its pointing to exchange-2007.rogerakl.com at IP address 67.68.103.87. I am not able to telnet at port 25 to delivery the email. Please use the URL https://www.testexchangeconnectivity.com/ and do the inbond SMTP Test and share the errors.Jasjit Singh Dhindsa | ITIL v3 | IASA Foundation Certified | MCITP: EMA 2010/2007 | MCTS: MES 2010/2007, OCS 2007 | MCSA: M+S | MCSE: M+S

I was able to telnet port 25 and test message went fine....maybe because i'm on the same network.. Here is the error message from the test: Testing inbound SMTP mail flow for domain administrator@rogerakl.com. ExRCA failed to test inbound SMTP mail flow. Test Steps Attempting to retrieve DNS MX records for domain rogerakl.com. One or more MX records were successfully retrieved from DNS. Additional Details MX Records Host exchange-2007.rogerakl.com, Preference 0 Testing Mail Exchanger exchange-2007.rogerakl.com. One or more SMTP tests failed for this Mail Exchanger.

Additional Details IP addresses returned: 67.68.103.87 Testing TCP port 25 on host exchange-2007.rogerakl.com to ensure it's listening and open. The specified port is either blocked, not listening, or not producing the expected response. <label for="testSelectWizard_ctl12_ctl06_ctl01_ctl01_tmmArrow">Tell me more about this issue and how to resolve it</label> Additional Details A network error occurred while communicating with the remote host. I can see that port 25 is blocked, and this is done by the ISP. are there any woraround this ? I am routing my email outbound using my ISP's SMTP server, but I don't know a solution for inbound. Thanks!!
