We have an old AIX server.  it is able to send email on its own to any email address.  Including over the LAN to our exchange server.   Recently we migrated to SBS 2008 from SBS 2003.  Now I am no longer getting the email sent from the AIX box.    The AIX can still send to normal internet addresses like gmail, but it is not getting delivered in exchange.

I suspect it has something to do with security, since the AIX, has no reverse pointers or any of that detailed DNS/MX stuff set up for it.

Any ideas?

Try setting up a receive connector for just that AIX box. and allow anonymous authentication.  Here's a link to a good set of instructions.

Do you mean that your linux server uses exchange server to send emails as an relay ? if so, please create a new accepted domain.

no the linux/aix does NOT relay through exchange.  It sends mail directly (using sendmail I think).  So for instance, I can send mail to my gmail from the aix even if the exchange server is down.  

The problem is just that the exchange server does not seem to accept the mail from the aix.  

I suspect it has something to do with security, since the AIX, has no reverse pointers or any of that detailed DNS/MX stuff set up for it.

Anybody know how I can get exchange to accept the mail delivered from this server?   Or how I can look at logs to see exactly why it is not accepting it, etc?

Does Powershell have you tied up in knots?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why
