We have a client that is using GFI mail essentials and security software. We would like to remove this software and put an external mail filtering solution on their systems. However, I'm not familiar with GFI or the steps to do this. I presume we just remove it from add/remove programs . The SMTP port in exchange still accepts on port 25 so I presume the filtering happens after Exchange has accepted the email so there is no need to make any changes when the software has been uninstalled? Is there a way of exporting the settings in GFI in case they want to reinstall at a later stage?
Any advise is much appreciated.
