We have an iSeries (AS/400) host that has a command (SNDDST) that allows you to use an external email server to perform mailings of messages and files from the host.
Everything was working fine with Exchange 2000. When the server guy upgraded to Exchange 2003 I can no longer send a distribution to any person who is in our domain ([email protected]). Emails to anyone outside of our domain work fine. This leads me to believe that the distribution (email) is making it to the Exchange server program.
I am not an Exchange 2003 guru, so I need some help as to where to look for some settings (on the Exchange 2003 server) that may be stoping internal emails from being sent.
