Gmail on the SORBS blocking list

I just tried sending a reply back to Vodafone customer services regarding an issue I've got with my online account. I used my Gmail account (of course) only to get the following sent back:

PERM_FAILURE: SMTP Error (state 8): 550 5.7.1 Mail from refused - see

After a quick check, I found that it was a Google assigned IP address. After doing a search of the SORBS database, it was confirmed. It's interesting to note though that the PTR record has changed from what was listed at the time of the SORBS database entry to but that would not avoid the block, since it is IP based. The change must have been for another reason.

Record Created: Sat Apr 22 04:30:03 2006 GMT
Record Updated: Sat Apr 22 04:30:03 2006 GMT
Additional Information: Received: from ( []) by (Postfix) with ESMTP id 670B611439 for <[email]>; Sat, 22 Apr 2006 13:15:05 +1000 (EST)
Currently active and flagged to be published in DNS
If you wish to request a delisting please do so through the Support System.

I noticed that Sun is one of the companies involved in SORBS, so I tried sending an email from Gmail to my Sun address but it went through okay, strange. Maybe Sun is part of it, but not actually using it. Anyway, it seems that people who are using SORBS can't currently receive mail from Gmail users.

The funny thing is that Google is part of SORBS too - so part of it, but blocked by it! If Google were using SORBS, then it would mean that Gmail users would probably be unable to send email to other Gmail users unless Google had something in place to always allow it, regardless of any blocking list or system. Maybe Google are using it, but I don't think they currently are.

Aftering seeing the current block myself and typing this post, I did a quick Google search and found discussion about this issue. It seems that Spamcop have also blocked Gmail, but at present the IP in question is not in the database. The blocks are due to Gmail not including the injecting user IP in the headers, which in one respect gives an element of privacy but something that nobody else really does and it also allowed spammers to hide.

I guess I won't be emailing Vodafone for a while, not from Gmail anyway. I wonder what other companies are using SORBS, that I won't be able to contact using Gmail? This is an example of when free email isn't always the best option but I'm sure it will be sorted out soon.

Two months have passed

Well, it has already been 2 months since my last post. Time really does fly, but not so much if you're clock watching. I was planning on posting in April, but had a lot of thingd going on and never did.

Anyway, the Snowbombing trip was excellent, I'll be going back next year. Next month it is Beachbombing, I'm in the process of sorting this out. It's only 69 for 3 nights so well worth it.

There is a lot going on in the technology world as usual but there are a few interesting things which have caught my eye. The firmware hack for the XBOX 360 DVD drive is one of them, it'll be interesting to see how that pans out and how MS plan to combat the up and coming piracy. Check out the video of a hacked unit playing a copy of PGR 3.

There is plenty of activity in the PSP world as well. Lots of interesting applications are being released, including alternative shells, emulators and a VNC type application. I've downloaded updated firmware versious a number of times, but it's always a choice between upgrading by choice and being forced to by the desire to play a new game which demands the upgrade. Forced upgrading is a smart move by Sony, partly to try and stop people running custom code and also to provide new functionality.

The days are getting longer warmer, so it'll be more of a reason to be outside with the portable gadgets and less reason to be inside on the computers. I'm wondering what my next gadget purchase will be. I've been meaning to get a portable GPS navigator for my car, probably the new TomTom GO 910. Although I think they are still a bit on the expensive side for what they are, but worth it when you're doing a lot of driving around and there is usually more of this going on in the summer.

Summer is coming, enjoy it!
