Not sure there’s anything we can do about a third party listing your IP address on a black list. Are you having any issues using the service we’re providing?

@Anoush isnt that IP one of the avasout servers ?

Re: Plusnet on a black list

SteveA — Mon, 17 Jan 2022 18:16:05 GMT

@Anoush - its not mine, it is, apparently, avasout-peh-004.plus.net

So I sent email (via the plusnet relay) and it was bounced with a message saying that the sender IP was blackisted.

Thanks a lot for getting back to us @SteveA

Can you please send me a PM with the outgoing email header, as well as the bounceback email header at all?

SENDER IP address black listing is something quite different from the detail in the OP.

Are you using Plusnet as your ISP / connection to the internet when you encounter this issue?

@Townman - I'm on PN, from home, I am sending all email via the outgoing PN email server ( relay.plus.net on port 587).

I sent the email and it came back as not being allowed to deliver because 212.159.14.20 id blacklisted by Abusix.

@adam945 - I'll PM you the headers on the email that came back plus the contents.

I've checked my IP address and that's also on the blacklist, probably a false positive but you need to get your details deleted or else get a new IP address................

Re: Plusnet on a black list

SteveA — Tue, 18 Jan 2022 20:27:40 GMT

It is NOT my IP address

212.159.14.20 is avasout-peh-004.plus.net

which is one of PN's servers....

So anyone using relay.plus.net to send email and which routes through avasout-peh-004.plus.net will be bounced if the receiving server uses the abusix black list.

Doesn't explain why my address is blacklisted as I'm not using relay.plus.net. Just an IP check - could be a whole block of IP's are being blocked. In which case Plusnet need to talk to Abusix...........

(I meant to post this earlier today but it looks like the internal response system we use when posting/messaging on the forums, sent it as a PM instead)

Hi @SteveA

I'm really sorry to see you're having issues sending e-mails.

I've raised a NetOps task with the headers you've given for further investigation.

As soon as we know more, we'll let you know, this should be by the end of the week.

Re: Plusnet on a black list

Hi @SteveA

I can see the task has been updated to advise that these type of listings normally expire within a week, providing that Abusix don't get further examples, however NetOps had requested an immediate delist yesterday.

Can you check if you're able to send e-mails OK now?

Re: Plusnet on a black list

SteveA — Sun, 23 Jan 2022 14:59:45 GMT

It didn't always fail - so I'll try sending a few to him and see what happens.

No problem @SteveA, let me know how it goes.

I am having the same problems.

I run an email gateway for a couple of businesses and whenever I was forwarding personal emails to myself over the relay.plus.net SMTP servers they are never received.

Our logs are full of the following.

NOQUEUE: reject: RCPT from avasout-ptp-003.plus.net[84.93.230.244]: 554 5.7.1 Service unavailable; Client host [avasout-ptp-003.plus.net] blocked using urired.spameatingmonkey.net; listed, see https://spameatingmonkey.com/lookup/plus.net; from=<XXXXXXXX> to=<XXXXXXXXX> proto=ESMTP helo=<avasout-ptp-003.plus.net>

If you go to this link - https://spameatingmonkey.com/lookup/plus.net

They show the offending emails sent from the plus.net IP's that are causing the blacklisting.

Hello @BroadbandUser

Thanks a lot for getting in touch and I'm sorry to hear that you're also having this issue. Can I ask, are you experiencing this issue while connected to other internet providers / 4G connections, as opposed to your service with ourselves?

Re: Plusnet on a black list

broadbanduser1 — Sun, 06 Feb 2022 18:01:23 GMT

No, this happens when I try and send emails over my plusnet broandband service using the relay.plus.net SMTP server.

Re: Plusnet on a black list

LaurenB — Mon, 07 Feb 2022 16:08:08 GMT

Thanks for getting back to us @broadbanduser1, thanks for getting back to us. The emails you forward to yourself, do these all come from the same address or multiple different addresses?

Re: Plusnet on a black list

broadbanduser1 — Wed, 09 Feb 2022 15:03:22 GMT

Happens to all emails I send through the relay.plus.net SMTP server.

Are you also experiencing these issues through your webmail account @broadbanduser1?
