[plug] Bounce Spam (Back scatter)

[Timothy White]

I was wondering how people minimise this? Dad is currently having
problems with a particular server (*cough* iinet *cough*) hosting mail
servers, and accepting mail for virtual domains, then deciding the
user doesn't exist so sending a bounce. Problem is, Gmail marks the
bounce as spam. I was hoping to limit the amount of this, with out
local mail server, so that any bounces generated are at SMTP time (via
remote systems) and it only generates a bounce for local recipients
(the correct way), so the bounce never leaves our system, never goes
through Gmail.

It would appear that the qmail server on iinet isn't configured right,
so I even tried an "Errors-To" header to see if that helped avoid
Gmail. No luck. So other than calling up iinet and abusing them about
their server sending out backscatter, what other ideas do people have?
Unfortunately it needs to originate from this gmail address, and it's
a pain that the bounces are marked as spam, as we NEED these bounces
so we can prune the contact list.

Thanks

Tim
p.s. iinet, I didn't want to mention you, but your the company giving
the most trouble atm with this list of address. I mean, if you tell me
250 then it means my message is ok. NOT THAT IT'S GOING TO BOUNCE!
