Try 'telnet localhost smtp'. I'm pretty sure you'll see the same
problem, i.e. something like 'Connection refused'
As said before, what java tries to do is:
1. Connect to System.getProperty("mail.host") on the smtp port (number
25).
2. If 1 failed connect to localhost on the smtp port
3. If 2 failed lookup mailhost (which is not the same as localhost on
many systems), if mailhost is unknown throw a UnknownHostException
else try to connect to mailhost on the smtp port, if that fails
throw a ConnectException.
The conclusion is that you don't have a Mail Transfer Agent on the
hosts System.getProperty("mail.host"), localhost, and mailhost.
Adding mailhost to /etc/hosts wont help, you have to install and
configure an MTA (exim, sendmail, smail, ...) somewhere. (Another
option is to set the property mail.host to a host that will act
as a mail relay for your host).
