I have been running SME v8.2 for our company e-mail server for several years and it works great. I now want to upgrade to 9.2. I have read the documentation regarding email in the release notes for 9.2 and don't see any issues that might affect me. My setup is Server and Gateway and has a public IP address but no registered domain name.
Are there any issues or differences that I should address before the upgrade? Thank you.
