Spam via Plusnet servers

Can Plusnet/anyone provide me with a full list of Plusnets MX mail servers so I can block them on our company firewall.
I'm fed up with the sheer volume of spam being forwarded to our domain via mx.last etc.
Today I've had to block IP range 84.92.6.01-84.92.6.11 due to hundreds of emails suddenly pouring onto our mail server mid afternoon from cnt.com and yahoo.com.
These addresses resolve back to fhw-sunmxcoreXX.plus.net where XX is the last 2 digits of the IP address.

Hi there,
I've removed the domain records from all of your domains referencing mx.last - this should stop all of the spam from coming through.
Hope that helps, please let us know if not.

@orbrey
Wasn't that a change that the user could have done for himself?

@NWB
I assume you are using the SMTP delivery option. Are you using autoturn?

@ Jelv
I would have done but for some unknown reason no MX entries showed up via the user cp when I looked earlier today. In fact I've only just seen the blog posting about the ability to do this as previously it was not possible.

Yes. But we don't receive mail from Autoturn as its always spam

Re: Spam via Plusnet servers

If you are not receiving mail from autoturn, have you still got it in your mx records? If so genuine mail could be ending up there if your normal mail server isn't available - or have you configured an alternative mx yourself?

Re: Spam via Plusnet servers

We will soon be adding a secondary MX record but for now all mail will go to our primary MX record.
I would rather mail bounce back undeliverable than end up amongst the thousands of spam emails currently queued up on Autoturn.

Re: Spam via Plusnet servers

If you are not collecting mail from autoturn, surely you've removed autoturn from your mx records. In which case how can spam end up on there?

Re: Spam via Plusnet servers

We have done this afternoon with the help of Plusnet.
Up until today we didn't know the option existed to remove it as previously we've been told it wasn't possible by support.

Re: Spam via Plusnet servers

I bet you were not the only one in ignorance of this improvement. I would have thought there would have been a case for emailing everybody that uses SMTP mail delivery.

Re: Spam via Plusnet servers

True.
There used to be a newsletter periodically from Plusnet with new developments but not seen one in ages and I don't get a great deal of time to sit browsing the Plusnet web site. Only by chance whilst I'm off with a broken toe did i sit down and have a browse.

Re: Spam via Plusnet servers

There still are newsletters - you can find copies of them on-line here
I can't however find any reference to mx.last. Cry

Re: Spam via Plusnet servers

Just saw this thread, and would really like to remove mx.last from our mail settings. Tried to search the formums for advice on best way to do this, but the search seemed to throw up all sorts of voip results to a search on mx.last, so I was wondering if you knew where I might find a tutorial.
I went to my domain settings where mail delivery is set to SMTP (at the top of the page) then in Additional DNS records, mx.last is listed. I see I can remove this additional DNS record, but when I try, I am warned that this is my only mx record.
Do I need to set mail delivery (at the top of the page) to other and then specify the dns settings for our mail server, or will these stay set?
Thanks,
Patch
