Problems sending email - getting a strange usermin message: Failed to open /home/


Just reinstalled a server, and seems to have everything running, but email is giving me problems. To make sure it wasn’t an issue when restoring my sites, I created a new testsite and a mail user for that site.

When I log into usermin and want to compose a message, I’m seeing this message:
Failed to open /home/ for writing : No such file or directory

Anyone know how to fix this issue?

BTW, the OS/distro is Ubuntu 16.04.3

I noticed that the folder .tmp under /home/ is not created
