ETRN on 2003 SBS Server
I have a 2003 SBS Server that I am configuring for the first time. I need some assistance in setting up their email for exchange. The Server is working beautiful except for the email part. I have configured the email system to use ETRN for retrieving emails from the domain host. I have asked my ISP to enable ETRN on their side which they say they've done. Now when I send an email from inside the network to an outside email address the person receives it. When I send an email address from within the company for example frank@frog.com to frank@frog.com it works great. The issue is when I send an email from home say frank@telus.net to frank@frog.com the email never arrives on the Server. If I check the ISP web mail system the email arrives there. I am not sure where the issue may be. We use an ASA5505, could this be blocking the ETRN requests? Our firm also uses many Blackberries; will ETRN affect the use of these devices?? Please advise, this is my first time setting up Exchange and I am not too comfortable with DNS. Please advise.
Also, this might help:

Under Exchange System Manager, go to the Connectors and right click on SMTP Connector. Then go to Advanced.
This is where the ETRN settings live.

Thank you for the input. I've checked the settings and all looks well there. Could my ASA5505 be blocking the signal somehow ? Could it de that my domain host didn't do something properly ?
There should be no problem with the firewall as your server is effectively the "client" in the case of ETRN as it downloads data from the ISP's server.
It would be worth doing some checks with the ISP to ensure ETRN is enabled.

Thanks for the update. I think I'll set it up the proper way using DNS instead of using the ETRN method. Since I've never done this before but am familiar with 2003 Server Standard is there anything I have to watch out for when I enable it ? Do I have to let my domain company know anything special ? Does my Server need a static IP address externally ??? Also, there are a few Blackberries being used, will this mess with those ??? I know I am asking alot. I thought this would be easier but perhaps I am making it more confusing than it needs ot be. My DNS skills are OK but it sometimes gets a tad confusing. Thank you.

Excellent, thanks for the detailed info. This makes more sense. Thank You and sorry about the delayed reply.
Did your ISP give you instructions to setup ETRN then?
Firstly you will need to specify the time and frequency for downloading ETRN mail.
You can specify a schedule and also need to specify which domains to allow ETRN for (enter your domain frog.com)
