Outbound emails go nowhere using exchange 2010

I can sned emails to myself in Exchange 2010 from both internal and external.

If I send from my old exchange server 2003, I receive the email in my mew email server 2010 but when i reply the email goes into (who no where?)

So I am guessing my outbound from exchange 2010 is not working, but it can receive emails from exchange 2010.  I have tested this using a internal email address and I have sent a email from my gmail account.  I received both but when I reply the reply never get back to me?

First of all, verify the DNS settings.

Make sure that Outbound port 25 should be opened for Exchange 2010 on Firewall.

Try by doing telnet eg-  " telnet exchangeservername  25" and try to send email from Exchange to any other remote domains like Gmail etc.

Also check it out your Outbound public ipaddress should not be in blacklisted.

Thank You!

No blacklist, I have another exchange server that I am moving away from and it is setup with the public IP.
I think you are sending me in the right direction...
