Re: [nznog] Sorbs blocking addresses
I'm assuming this means that all customers sending their own mail will now have to use the xtra smtp servers?
On that subject, I notice that etrn.iconz.co.nz has (probably recently) started using SORBS's dynamic DNS blacklist, and I've had reported e-mail complaints from Xtra and TelstraClear DSL customers today. Generally, when we find this happening, we contact the sysadmin on the remote end and advise them that they are likely blocking a whole set of e-mail they want to receive - harder when it's an ISP. With Xtra's Port 25 push, it could be that ICONZ have decided to have a flag day, forcing everyone wishing to communicate with them, running a (small business) mail server on a DSL connection, to now use their upstream ISP's mail server - losing the ability to diagnose mail routing after it disappears "into the black box". Is this the future? Craig
A large Telecom subnet has been black listed by sorbs (listed as dynamic e.g. dial-up/dsl/etc), this happens to include some/all of their mail servers as well as many customers (like the organisation I work for). I understand that it's currently being worked on by Global Gateway (APNIC entry for subnet). This has caused major disruptions to us and many other Telecom customers (to say nothing of Telecom themselves). Later'ish Craig

A number of announcements have been made by SORBS in various locations - there is an issue with slow database updates currently and this has caused a delay between listing of subnets in the DUHL and the inclusion of the exclusions for the static addresses in the same subnet. Unfortunately I cannot stop the and restart process or it will make the problem worse for affected users in the 207.x, 208.x, and 210.x ranges. It should clear within the next 24 hours (looking to be around 6-12 hours based on the current timing), previously the maximum delay has been 30 minutes. The problem has been identified, code has been written, and will not be an issue in the future. Regards, Mat

Depends, would over 6 months ago fall into the realm of recently?

Actually, its no harder.

A future full of wildly innacurate assumptions? I HOPE NOT!! Xtra are more than welcome to update their records with sorbs, resolving the problem.
