[H-GEN] Double Delivery

The summary is that you are subscribed to the list twice.  The appropriate
address for this is either owner-general at humbug.org.au, or
postmaster at humbug.org.au (or you could unsubscribe your duplicate address
;) )

DS9.hcit.com.au has IP address of 203.63.166.4 .

*sigh*.  RFC1918 addresses in mail headers are _not_ helpful when tracking
down where mail is going (ie, caliburn did not sent it to RFC1918
addresses).  Lets assume that 192.168.2.185 is the internal IP address of
one of the hosts that would accept mail for:

sunstatestamps.com.au, which has MX hosts of:

	MX 10 server.sunstatestamps.com.au -> 202.5.165.129
	MX 20 wormhole.hcit.com.au         -> 203.63.166.12

Well, not really.  Lets see which subscribers get mail delivered to hosts
in the same IP block (cue, 'heres a script I prepared earlier[1]') :

$ findsubsinipblock.pl --subscribers general --iprange 202.5.165.0/24 --run
rickp at sunstatestamps.com.au is in 202.5.165.0/24 via server.sunstatestamps.com.au (202.5.165.129)

And lets not forget the other host:

$ findsubsinipblock.pl --subscribers general --iprange 203.63.166.0/24 --run
rickp at hcinternet.com.au is in 203.63.166.0/24 via wormhole.hcit.com.au (203.63.166.12)
rickp at sunstatestamps.com.au is in 203.63.166.0/24 via wormhole.hcit.com.au (203.63.166.12)
rickp at hcinternet.com.au is in 203.63.166.0/24 via ds9.hcit.com.au (203.63.166.4)

So, caliburn isn't unwell, but you are subscribed to the list twice.  You
wish to take this matter up with general-owner at humbug.org.au , or
properly unsubscribe your old email address.

[1] findsubsinipblock shows all email addresses in a given list which are
    delivered to hosts in the same IP block.  Most useful when you have a
    'few' lists to look after.  I still haven't gotten its run time down
    to acceptable levels when more than ~1024 domains are involved :(
