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; <wapterix(a)mail.com> 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 relays.mail-abuse.org 203.96.92.15 not RBL filtered by inputs.orbs.org 203.96.92.15 not RBL filtered by outputs.orbs.org 203.96.92.15 not RBL filtered by manual.orbs.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? --cw --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
