DMARC rejection

[mikep6dd]

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.

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.

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.

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.

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.

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