[Javaemailserver-user] UnknownHostException on startup

[<jav...@li...>]

I downloaded the latest version of JES just now and updated the user.conf,
mail.conf (following the instructions in the pdf file for non-root
privileges) en start it up using mail.sh (on my mac).
I get the following exception on startup and all the emails I try to send
are rejected:

Any idea what I might have forgotten?
