At present, some of my outband email is sent through XTRA's
mail-server(s) as they block outgoing SMTP access when you are
inflicted with Jetstream/Jetstart through Xtra.
Not that I really mind all that much, it works pretty much flawlessly
and Xtra are arguably being good people by blocking nasty evil users
from injecting spam into other peoples open-relays (perhaps they
block other ports too --- maybe someone from Xtra can comment?).
Now, this just occured, which again doesn't really bother me in this
instance, but I am curious as to _why_ this was blocked. The DSN I
received says this:
Reporting-MTA: dns; balthamel.xtra.co.nz
Arrival-Date: Sun, 17 Jun 2001 23:13:47 +1200
Received-From-MTA: dns; tapu (210.55.42.93)
Final-Recipient: RFC822;
Action: failed
Status: 5.1.3
Remote-MTA: dns; mail-com-bk.mr.outblaze.com (205.158.62.36)
Diagnostic-Code: smtp; 553 5.3.0 Mail from 203.96.92.15 refused. Blacklisted.
yet when I check the common 'blacklisting' mechanisms I find
nothing:
tapu:~$ rblcheck 203.96.92.15
203.96.92.15 not RBL filtered by blackholes.mail-abuse.org
203.96.92.15 not RBL filtered by dialups.mail-abuse.org

203.96.92.15 not RBL filtered by spamsources.orbs.org
203.96.92.15 not RBL filtered by untestable-netblocks.orbs.org
203.96.92.15 not RBL filtered by spamsource-netblocks.orbs.org
so I wonder what else is out there that is used to blacklist evil
people? And why is Xtra in this list?
