They already use the rDNS in the mail headers so that can internally
identify the locale without having to make it overt.

Howard,
I'm not sure what the issue is. The reality is if that you use your real
name and give any indication of your locality then unless your name is
Smith or Jones, you probably will count on one hand your matches. For
instance I usually say I live in the Southern Highlands, but anyone can
find my real number and address without any trouble.
If I was an ISP I would be wanting to use geo-focused names for my
routers and DSLAMs so that I can easily find correlation of network
issues. I am not sure that it is the ISPs responsibility to obfuscate
mail headers and the like. And it really would make troubleshooting
hard. (I get frustrated enough working with customers that refuse to
populate their DNSes with names of their network equipment and such -
having to keep a "telephone book" IP addresses in my head is pretty
painful).
If you really want to be private I think people will use email
anonymizers or even just a gmail or somesuch account.

Subject: [SLUG] ISP info leakage
Out of curiosity I looked at the source of a recent email and discovered
that the sender's ISP had identified the suburb in the FQDN of the DSL
IP that the sender used to connect to that ISP.
A quick look in Sensis against the sender's name and I came up with a
name and address match only one suburb away.
The moral of the story is - Don't trust Optarse...
