Emails bouncing due to spam concerns

AlanL4 — Sat, 23 Aug 2025 11:42:49 GMT

Quite often I find my talktalk emails bounce from reputable recipients such as Yahoo and Hotmail because of spam concerns. I believe Talktalk should be able avoid this happening. Here are details of the latest occurrence of this. Please follow the link at the end for Microsoft's suggestions for fixing this:

hotmail-com.olc.protection.outlook.com[52.101.10.4] said: 550 5.7.515

Access denied, sending domain TALKTALK.NET doesn't meet the required

authentication level. The sender's domain in the 5322.From address doesn't

meet the authentication requirements defined for the sender. To learn how

to fix this see:

Good morning AlanL4. So just to confirm you are unable to send emails to certain domains?

Sometimes - this problem happens intermittently, but sufficiently often to be worrying.

@AlanL4, could you double check o your end to see if your inbox is not full as this maybe one of the reasons to some of the emails you are receiving ending up in the Spam folder.

@sabelo-TT easily done, but I think you have misread the customer's issue.

They are not receiving mail in spam, but mails they Send are ending up being bounced due to their emails being marked as spam.

Totally agree - I am having real issues sending to Hotmail addresses. They bounce back as undeliverable :

The following organization rejected your message: eur.olc.protection.outlook.com, hotmail-com.olc.protection.outlook.com.

Diagnostic information for administrators:

Well said @sae999.

@nambuso-TT: TalkTalk has gone very quiet on this. It's nearly 2 weeks since you said "I will send this through to our specialists". Any news please?

I am also receiving this message when sending emails to outlook.com addresses and gmail addresses. I have also had a NDR saying

550 5.7.1 Reject for policy reason

Does anyone know how to rectify this?
