Hi There!

We are seeing that Voyager customers are blacklisted by mta.xtra.co.nz. If we telnet from any Voyager IP to mta.xtra.co.nz we get "421 service is not available" and then immediately disconnected. 

We don't have any issues with any other providers. Likewise I am not having trouble accessing mta.xtra.co.nz from other addresses. 

I have tried calling spark business support who categorically deny they block ip's despite the evidence. I was told to send screenshots to an email address, but when I followed up with the same team a few days later not one person knew of this address. 

Voyager say they can't do anything, Spark deny it's happening.

I can't seem to find someone who works in the right department (despite a few good people who have tried to help) who can resolve this. 

What do I do?

I've seen this before - you might want to try the NZNOG mailing list.

Does voyager provide an email service?
If so then its their responsibility to deal with the xtra mail administrators and those guys usually talk via nznog - its not generally for customers of ISPs.

However if voyager do not provide an email service, then it is up to the spark customer to lodge a fault saying they cannot recieve incoming mail from ip addresses x.x.x.x to y.y.y.y

We dont provide an email service for our customers specifically because we dont want to deal with this stuff.

It sounds like voyager may have had a customer sending out spam - I assume they block port 25 outgoing by default on all new connections to reduce this risk.

Also its usually only a /24 that gets blocked so voyager may be able to assign you a different ip address to get your mail through again. Though i wouldnt expect them to be able to do this easily.

He's not the operator, he shouldn't use NZNOG. As above, if it's Voyager service they should start working with Spark to remove this block, if it's a user-run server then the user should work with Spark.

If regular channels at both Spark and Voyager don't work, then a post to the NOG list wouldn't hurt. Hell, I'd happily post one on his behalf if he PMd me.

The problem is right now, I can't find the "proper" channels at Spark. It's just insane this could go on like this for so long.

These customers which are blocked, are they in dynamic IP space?  In which case it's pretty normal to be disallowed from sending.

If not then Voyager should request unblocking from Xtra for the affected range(s).

As best I can tell it's ALL Voyager IP's in the static spaces. I don't have any connections with them on the Dynamic.

The problem is figuring out WHO Voyager contacts.

Considering all the Spark Business Support staff have so far shrugged their shoulders...

I used to be able to email cts for this stuff, but that now reroutes to SALES!

Let Voyager sort that out, as a carrier they will have contacts not available to the genpop.  Bit surprised they said they can't help you.

Can you check the voyager ip address using a mx blacklist checker for the ip address.

Im on voyager and am getting 220. When we signed up we where blacklisted by I think mcafee due to them thinking it was a dynamic IP address however Whois records proved otherwise and they reversed the block.

mxtoolbox shows as all clear. I have checked a bunch of blacklists, all clear. Seems xtra specific.

MS don't advertise their blacklists either.

Why are you trying to connect to mta.xtra.co.nz?

In almost all cases you should be sending outgoing Email to your own ISP's mail server for relaying.
If you're trying to send to xtra.co.nz users directly, then you should be following the MX records:

$ host -t mx xtra.co.nz
xtra.co.nz mail is handled by 10 mx1.tnz.mail.yahoo.com.
xtra.co.nz mail is handled by 20 mx2.tnz.mail.yahoo.com.

Getting through to the right people at some of these large ISPs can be difficult. It is one of the advantages of dealing with a small provider.

Spark has replied asking for more information, let's see what happens when we give it to them.
