Topic # 138943 22-Jan-2014 14:14 Send private message

I have just got an error message:


   ----- The following addresses had permanent fatal errors -----
<target email address>
    (reason: 550-The sender 60.234.4.69 is in a black list at bl.spamcop.net)

The <target email address> is the person I sent an email to using mail.orcon.net.nz as my SMTP server.   The IP address shown is an Orcon host according to ip-lookup.net.

Do Orcon have a black listing problem here?

Looks like you've got an issue with your IP address. Someone has flagged some emails from your IP as SPAM

Yup... every few weeks they seem to. We're routing our emails via another ISP at the moment to get around it.

Your recipient is subscribed to Spamcop and Spamcop think that IP is a spam source.

You'd be best to log a proper fault with Orcon support IMHO, to ensure they're addressing it. They may be able to provide an alternative, non-blacklisted SMTP relay option too.

I think they do.

One of our suppliers on Monday who obviously also use Orcon as a mail host/SMTP server.

The IP was the same (60.234.4.69) and our host (Firstwave.com.au) reported their email to us was rejected because of that IP addresses poor reputation.

Looks like one of Orcon's servers has been used as a relay, or someone has been sending lots of Spam.

Yap, had clients who have had the same problem. I tell them not to use the ISP for sending out email, as it is now a common occurrence for ISPs to get their IPs blacklisted, and it is frustrating to get them to fox it because their front one call centre staff often don't know about this type of problem unless you escalate it

Hi Guys,

Unfortunately some of our mail clusters have been black listed, there should be something on the network status page now. Sorry about the delay.

Just to clarify - 60.234.4.69 is not my ip address but it is reportedly owned by Orcon.

If you have a reliable ISP you should be able to generally rely on using their SMTP smarthost, with the caveat that obviously all email sent by all of that ISP's customers is likely to pass through the same set of IP addresses, exposing you to the reputational risk that their aggregate customer base also shares.  The ISP won't want their IP's blocked, so one hopes they would pay attention to any reports of this, and act quickly to deal to it and get themselves delisted.

Direct SMTP from your own connection, to bypass your ISP's blacklist situation, is an option, but only for static IP customers (realistically, dynamic IP blocks are frequently blocked simply because that's what they are, and probability analysis would indicate that you're going to be more generally reliable sending email thru your smarthost than directly). Many ISP's block outbound connections on Port 25 from their customers in acknowledgement that for the most part, these are spam emails that they don't want leaving.

The alternative is to find a service provider that has SMTP-AUTH capability and that you can talk to over Port 587 (bypassing any Port 25 blocks).  There's third-party email service providers that offer this.  They may also support allowing unauth'd relay from you based on a fixed IP.

Opinion entirely personal.

I agree that in the ideal world that would occur. But I think some ISPs don't consider email a core service these days, as it is something they provide for free, so they may not have the resources to be continually monitoring their IPs reputations. I am not sure how an ISP would find out that thier IP is blacklisted without checking it in a website like MXtoolbox, or a customer reporting it to them. Or does the IP owner get emailed when there is a problem? If a cusomter has to manually report it, that would result in a lot of wasted staff time I am sure, which would make it expensive for an ISP to deal with.

 I have had so many problems with clients over the last year, with their ISPs SMTP server IPs getting blocked due to poor reputation, and this has included many of the large ISPs in NZ. The solution for businesses, is to use a domain email address, and use the SMTP server of their email provider, and not host the email address with an ISP. Basically you use an email provider, where email is one of their core services where they provide immediate support, and they will fix any reputation problems immediately if they do occur. I haven't had any problems with non ISP email providers and web hosts. Even gmails IPs never seem to get blacklisted.

I have found that with ISPs, the problem is really getting through to the right person to fix it. If you contact an ISPs helpdesk , the front line staff don't really know what to do. They say they have to escalate it in their system but won't put you in direct contact with the person who it is being escalated to. It is certainly a frustrating problem to deal with, and I mainly find it is restricted to ISP mail servers and seems to be an across the board problem with NZ ISPs from time to time. There really needs to be an easier way to replort blacklisting problems to an ISP such as a simple form that can be filled in

And this is why I use own box to do SMTP behind my static IP address..... More users you get the more spam you still start to deliver...

Try emailing the notification you receive to [blacklisted at orcon.net.nz] (changing at to @ and removing the spaces)....

Will this work for blacklisted iServe servers too?

Over Christmas I found several messages that had been sent via my iServe hosted websites (i.e. forms on my websites which PHP emailed me the form contents) had been marked as spam by Gmail (I use Gmail for all my own email). Gmail usually gives a reason as to why it thinks messages are spam, and in these cases it said it had encountered a high amount of spam messages from iserve.co.nz (sorry I didn't keep a copy of the exact message).
