It may be a pain the *** for ISPs to deal with blacklists, but email is one of the things what we pay them (a not inconsiderable amount) for.

I had further bounced mail yesterday (to talkTalk) while in the middle of a conversation so it was doubly frustrating. However it was OK on the 2nd try.

Be nice to know more about why it happens and how it's resolved. And if a non-delivery email can be generated, why not one when service is restored ?

It happens because customers get infected and their machines start spewing out spam. Clearing it up involves blocking the infected customer and then running around trying to get hostile and often unhelpful spam list providers to clear the blockage. Often there is little the ISP can do to clear third party lists. The ISP is the proverbial meat in the sandwich.

Fair enough. But if they had said that they had a problem and were working on it, I would have been satisfied and left it at that. But they flatly denied it was their problem to fix. They blamed overseas ISPs and said I should talk to them. The foreign ISP would not be interested in me because they rely on the SPAM control provider and the SPAM control provider would not listen to me if I was not an ISP.

So often the problems experienced by companies, like Orcon, can be blamed on their lack of communication with their customers. I once upgraded from an ADSL-only account with Orcon to one with a phone service included. That was a nightmare I do not wish to go through ever again. I seemed to deal with a myriad of people who were not talking to each other and didn’t do what they said they would.

In the case of spam blacklists and large ISP based mail services you can pretty much say there will always be a level of blacklist issue, its just the depth that changes. Why do you think Telecom (Xtra) dumped it all on Yahoo all those years ago, to move the problem to a dedicated email provider and that was still a huge mess.

Mr Orcon, When are you going to get this sorted ?

After confirming email was working again last night, I'm now re-sending bounced emails from yesterday. Two went through but now they're bouncing again.

Bugger this for a joke.

If you ever ran an ISP's mail platform of any significant size you would become aware that its a constant whack a mole of clearing blacklists, and blocking compromised customers while allowing your customers to send mail however they please. This is one of the reasons why ISP's hate supplying email nowdays and would be much happier if customers used specialist email providers.

The thing is that even specialist email providers get blacklisted. One way around it could be for every email account to have it's own dedicated IP, rather than sharing the same IP of the sending server, but people don't want to pay for that. People seem to think email shouldn't really cost anything or a minimal amount, but then expect it to be ultra reliable. But providers are responsible for making sure their IPs remain clean, and none of their users are spamming

Something has gone wrong at Orcon. The number of SPAM rejections has been increasing. It has now become almost impossible to send an email overseas. They are mostly bouncing.
