What's changed relating to localhost then?

I've just updated to 5.2-BETA today and have noticed that my spamd is 
now rejecting all connections from spamc because they are not coming 
from 127.0.0.1 any more. It's now using my public IP address of 82.x.x.x:

Nov 22 14:38:30 womble spamd[657]: unauthorized connection from 
82-32-25-111.cable.ubr04.azte.blueyonder.co.uk [82.32.25.111] at port 49167

I noticed somebody reported a similar thing earlier.

I'm actually in the process of reverting to a -current of 
2003.11.14.00.00.00 because my xl0 ethernet card is acting up as 
mentioned in another thread so I want to see if it works with that 
kernel. (Can't go further back due to statfs).

Also one of my machines running 5.2-BETA just hung dead within 5 minutes 
of booting. I don't have DDB etc configured though so can't tell why.

Matt.
