ETRN on 2003 SBS Server
Posted on 2008-06-21
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 email@example.com to firstname.lastname@example.org it works great. The issue is when I send an email from home say email@example.com to firstname.lastname@example.org 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.
