The current send mail action calls `uname -n` to add the hostname to the 
subject line. This may not be in your version(?) but it's easy enough to 
add if not. See: 
https://github.com/fail2ban/fail2ban/blob/master/config/action.d/sendmail.conf#L17

In terms of a single configuration across servers, you can use the `-c` 
flag with fail2ban-client to specify the configuration folder. You could 
use this to point to a network share folder with the config inside…
