Reporting Phishing Fails with Authentication required Message

[Morgai]

Hello

I've just been trying to report a Phishing email to my bank and to the gov.uk service. Both of these memails returned with the following message:

Your message did not reach some or all of the intended recipients.

      Subject:     FW: We require you to re-authenticate your account

      Sent:  03/05/2025 09:06

The following recipient(s) cannot be reached:

      'report@phishing.gov.uk' on 03/05/2025 09:06

            550 5.7.1  Reject for policy reason

I have resent the message using another email service I use without problem.

It looks like TalkTalk are blocking sending the reported messages!

P.S. emails to other recipients from my talktalk account work fine, this is a "tiscali.co.uk" account.

Regards Doug

In recent months they have stopped allowing these to be sent as a forwarding message, @Morgai, presumably because it looks like sharing Spam?

It seems to work if you create a separate email and send the offending email as an attached document or screenshot.
