DMARC rejection

mikep6dd — Thu, 02 Jan 2025 16:06:55 GMT

Just tried sending an email, first using tiscali.co.uk and then talktalk.net, both addresses of mine, and both were bounced back at me as being rejected under 'DMARC' by apparently Outlook. First time this has happened to with any of my emails to anyone and I've emailed this particular receipient, a relative, on a number of occasions without problems. His address is pobox.com, which is apparently part of Fastmail.

Any enlightenment would be appreciated.

Join the club. TalkTalk email servers are being rejected by lots of ISPs. You mention Outlook. I have reported of GMail.

Hi mikep6dd, please send me a personal message with the affected sending and receiving email addresses. I'll then add you the incident I'm raising.

Why bother asking various people to provide individual addresses. It is as plain as can be that this is the talktalk servers ie, multiple addresses being rejected by multiple other ISPs. It's completely generic and not down to any individual user.

I'll tell you why. If I open an incident without sufficient examples of the issue the incident will be closed immediately. I'll then have to waste time reopening it and while I'm doing that and answering questions both ways I'll not be helping other customers with other issues that I can fix. I've worked here for 18 years and know better than to raise an incident without examples.

Ady,

Thanks for that comment and I am sure we appreciate all the help we can get. With your experience, it should be possible to escalate this issue internally. You can see from the multitude of alerts in this forum, and from the nature of them that this is not about individual accounts: it is a single point traffic issue with numerous reputable mail servers rejecting anything from TalkTalk mail servers. At the same time, the TalkTalk service status page is claiming that all the systems are working correctly. That is just plain nonsense as this has been going on for quite a while: my own experience suggests at least a month.

The current situation is that it is possible to receive on TalkTalk accounts, but not send anything reliably. I for one have had to switch to sending everything via a Gmail account and making sure to change the sender if I reply to anything.

To raise it I need the sending and receiving addresses, IP you sent from and confirmation that this happens when you send directly to 1 email from webmail. I've already been told by the team I push it to that they're only seeing mail forwarding causing this problem.

Hello Ady

The receiving address in both incidents was XXXXXX@pobox.com. My first attempt at sending was from Xxxxx@tiscali.co.uk and the second from my other account mmpenk@talkalk.net

Just to be clear, neither of these was forwarding; both were straighforward replies.

There are two sorts of forwarding. Automatic where the mailbox option is set to forward everything and manual where the user forwards a received email. However its doesn't much matter which is being described by the support team as the problem lies with direct brand new emails. Therefore I agree with mikep6dd and the support team need to revisit this more seriously.

I can send test emails from my tiscali address via the smtp.talktalk.net server and it does not arrive at either Gmail or Yahoo. It has been this way since at least early December.

@mikep6dd, I've removed your private email address from public display. If you look back to Ady-TalkTalk's message from Friday, you were asked to send the information by personal message, as those details should not be given in the public thread.

If you click on Ady's name /avatar you'll reach the area in his profile from which you can send a PM.

@mbsharp, please don't follow up on this thread.

It makes it very complicated and confusing whilst trying to reply to the original poster.
