Some emails sent by users get rejected by the remote mail servers because in the email header the "from address" doesn't match the real domain address. Usually, I get error #541 from the remote server.
Could you please help me fix this issue?
Here is the config in our company. We use Exchange 2007, with a separate static IP address for the mail server. Exchange is running on Windows 2003 Standard SP2 which is also AD controller. The AD domain differs
from the web-domain. Please, see the details in the code snippet attached.
What would be preferred fix for this problem? Many thanks, Johnny
