Sorry for the delay in response.

I created a new VM with Server 2025.

I didn't exactly recreate current environment because I didn't want to install versions with known vulnerabilities.  I got it as close as I could.  I am still having the same problem with sending email notifications.  Here is my current setup:

Firebird
	Original Server   3.0.4.33054
	New Server w/Latest Software   3.0.13.33818
	New Server w/Older Software   3.0.13.33818

Java
	Original Server   8
	New Server w/Latest Software   Microsoft JDK with Hotspot 11.0.23+9
	New Server w/Older Software   8

Apache Tomcat
	Original Server   9.0.16
	New Server w/Latest Software   10.1.8
	New Server w/Older Software   9.0.115

Here is the webpage of "errors" that comes up when I test:

HTTP Status 500 – Internal Server Error

Bill,

why are you moving to Tomcat 10 when Tomcat 9 isn't end of life yet? Did the vendor recommend Tomcat 10 with their application?

My advice would be to only change one thing at a time and then test it.

In your case:

1. Move your old working software stack to the new machine (old java, old tomcat, old everything) -> test it 2. Create a second tomcat 9 (download the latest one) directory next to the old working one, stop the old tomcat and copy everything from old-tomcat9/webapps to new-tomcat9/webapps. Also, check if any other file is present in the old tomcat (you already mentioned you a files.xml, etc). Also copy these files to the new tomcat directory. 
Maybe even check contents of files, they may have been changed in the old tomcat directory. Test it!
3. Update to java 11. Test it!

And so on.

Sebastian
