DMARC and DKIM settings

Angela91 — Sat, 12 Oct 2024 13:58:42 GMT

Once again, email from a dsl.pipex.com account (of nearly 30 years of use and bill payments) does not reach the recipient on a gmail.com address due to the receiving domain's DMARC policy.

TalkTalk don't seem to have grasped the importance of DMARC and DKIM records, or at least they don't seem to have bothered with them for the "smaller" unsupported domains. This means that a lot of email leaving TalkTalk, particularly from the domains which it bought and promised to maintain in perpetuity, doesn't always make it to its destination untouched by spam filters. Google, for instance, recently upped their checks and will often sideline emails into their Spam folder from servers that don't have DMARC and DKIM records .

TalkTalk, please, please will you get this fixed. It should be a one off fix but bring enduring benefit to your poor customers.

Hi @Angela91 very good question and obviously one I can't answer, but your post has been escalated and you should hear on Monday.

Hi Angela91, I've asked the team to take a look at your comment.

What happened with the follow up on this? I'm having problems with my old dsl.pipex.com addresses too and DMARC verification seems to be the issue 😕

Hi @fmob22 great question to ask on a Friday afternoon just as the last person has left for the weekend.

If you still have an issue could you please start your own thread and the TT team will respond on Monday.

Interestingly I've been having DMARC issues for some time with talktalk and dsl.pipex.com addresses.

My mail forwarder has told me it's a talktalk issue, so would be great if this would be fixed at last.

It would be great if you, and anyone else affected, would each create a thread. Surely TT will have to take a bit more notice then, she said without any real hope that TT considers its customers in any of its actions

Hi @Angela91 great suggestion. Let's hope the others take the advice!

Re: DMARC and DKIM settings

Angela91 — Fri, 01 Nov 2024 20:25:05 GMT

The thread has been open for a long enough that it is quite reasonable to ask at any time, what TT might be doing about it. This is a long standing issue and emails are not reaching their intended recipients whether inbound to a TT customer or from a PIPEX address to long-standing correspondents. It was the last straw when TT managed to stop one time passcodes from reaching their destination last weekend. This had been working up until 10 October so unnecessary, un-thought through, undoubtedly untested changes have been made to mail servers. Why is left to the long-suffering customers to not only flag the incident, but also diagnose it and point out the remedy?

Re: DMARC and DKIM settings

Angela91 — Fri, 01 Nov 2024 20:25:41 GMT

Great question? Please keep posting and try and get TT's attention and the problem fixed

Re: DMARC and DKIM settings

Angela91 — Fri, 01 Nov 2024 20:29:12 GMT

So Ady, the customer suffers, flags the problem, diagnoses the problem, advises TT of the remedy. All TT has to do is implement the fix. What is taking so long? OTP were reaching me until approx. 10 October. TT changes have again broken more than any much-needed improvements they might have been trying to deliver. Please get this fixed.

That Monday did not have a date on it! Perhaps we can agree that Monday 4 November will be the date that this gets fixed if it has to be a Monday.

Well that stirred things up a bit... It's a shame issues happen 24 hours a day, 7 days a week and not just when support are in the office 🤣

On Angela's suggestion, I too have started a thread with my DMARC issue. Would be nice to have this problem sorted for sure. Thanks.

Hi all, each post on the thread pushes the thread back down the queue so I can only apologise for the delay in getting back to you. I've sent another chase to the email team to ask them to investigate. I'll let you know what I hear back.

Hi all, the email team have said you need to be sending from the TalkTalk email servers. Currently it seems you aren't.

Email Settings can be found in the Email Settings Help Article.

Ady, unbelievable response!!
If smtp.talktalk.net is not a TT server, I am not sure what is.

Re: DMARC and DKIM settings

Angela91 — Mon, 04 Nov 2024 10:58:25 GMT

Surely an increase of messages in a thread shows that multiple people have the same concern and should therefore be pushing the thread UP the priority list. Failing to understand the process criteria here and know that it is nothing like when I ran a Helpdesk. (Apart from the fact that we were customer-centric, sought to understand the issue, diagnose and resolve it. Except that for TT the customer has more understanding and has done the diagnosis so that leaves the matter of resolving to the customers' satisfaction.) Over to you TT. Please don't tell me I am not using your settings when my outbound mail is using smtp.talktalk.net.

Re: DMARC and DKIM settings

pbar100 — Mon, 04 Nov 2024 13:13:25 GMT

I know, I'm as stunned as you are. You just know that when tech support staff say something like that it won't get fixed.

Anyway yes I'm also sending from talk talk servers using the recommended settings.

Thanks.

I'm sorry, that's probably my fault 😮 The error I included in my post mentioned mail147c50.megamailservers.eu. There's a reason for this...

I have a domain, lets say mydomain.com. I use the email address me@mydomain.com which is mapped to a dsl.pipex.com address via an alias at my hosting company. So the email leaves Thunderbird using the TT smtp server but gets passed around a bit.

I think someone has been messing with settings somewhere though. As of today, I can't send emails from Thunderbird with my email address set to me@mydomain.com - I get this warning: "Sender address rejected: not owned by user 3@10880114.". So now I have set the sending email address to me@dsl.pipex.com to be able to send emails! I wish I'd never said anything now....
