Hello Davide,
I read your opinion regarding this issue and read the whole thread.
I strongly agree with the fact that it should be a closed relay by default (as most 
people obviously do), we all should be doing everything we can to decrease the 
ever-growing plague that is spam!  However, I also understand your point-of-view, but 
am pretty sure that the proposal of including only the private networks would be 
sufficient to avoid at least 90% of the mails that you are worrying about!

10.0.0.0/8
172.16.0.0/12
192.168.0.0/16

+ Beside these, there is Microsoft's 169.254.0.0 range of default IP addresses that 
are allocated to systems when they are unable to obtain address from a DHCP server.

If you include these three or four ranges as default configuration, you'll deal with 
most dummy users that don't care to read the docs... and provide a good basic 
configuration for a lot of situations in which XMail is used on the Internet!

I really hope you'll reconsider your decision! :-)

Best regards,

Frederic

  I must agree completely.  Every email server should ship as a closed relay.
  XMail supports SMTP AUTH by default, so an end user could still relay simply
  by enabling SMTP AUTH in their email client software.  Shipping XMail as an
  open relay only serves to create more of a problem (email server gets turned
  into a spam cannon; email server gets blocked by every major ISP).
