Is anyone else having problems with mta01.xtra.co.nz and mta02.xtra.co.nz mailservers being listed on international DNSBL blacklists?


Just using mxtoolbox.com and they return listings. 


I have a case open with Xtra's "Complex" technical support and wouldn't mind input from other people who use DNSBL's that are failing to receive mail being sent from mta01 and mta02.xtra.co.nz.

Happens all the time to ISP mail servers... presumably due to users on that ISP being infected with malware and being used as a zombie spam bot.

Vofadone's where blocked a couple of months back if I remember rightly.

Doesn't take much to get unblocked.

Everyone's listed in SORBS. No sane administrator uses it.




I finally have fibre!  Had to leave the country to get it though.

Thanks for your comments.

I wouldn't go so far as to infer people using SORBS are insane, considering they weren't listed there yesterday. Or the day before.

There are a number of people obviously still using it as a blacklist provider. Systems like these work best when problems are detected adn then rectified.

As part of my job I track down spammers and get them blocked off as soon as possible to ensure our mail servers don't get listed but even with the best email filtering appliances some do get through. Typically it always happens at some ridiculous time in the morning and by the time you pick it up when you get to work it can be all but too late.

Getting off the lists is normally pretty easy but sometimes it can still take a day which is a very long time when your helpdesk is taking heat by affected users.

It happens to everyone at some point unfortunately, and here to Xtra despite how much they have locked their systems down.

Thanks "insane" that's a helpfully reassuring comment. Nice to see these instead of comments that aren't. Appreciate your work.

The true moral of the story is that email is not as a reliable delivery mechanism as people think.

Generally speaking, everyone I've ever met who used SORBS no longer does.  Mostly because they operate an extortion approach to delisting.  If you are picked up for being dynamic, the admin requires you change your reverse DNS to comply with an RFC he/she wrote which was rejected.  If you are picked up for spamming (or a former occupant of your address space was) then he/she requires that you pay a "donation" to an "approved charity".  Yes, even if it was a former occupant of the space and you just got assigned it.  He/she says that "you should be more careful next time".

This was one of the main reasons we ditched Xtra years ago. They were on the Orbs black list and we had problems receiving email from people..
