Tiscali not receiving GMail

[GWEDWA]

Since at least January 2025 when I attempt to send a message from my Gmail account to my tiscali mailbox I get: "Message Blocked

The response from the remote server was:

550 5.7.1 Message rejected per sender's DMARC policy - OXSEU001_514"

Hi Gruff,

Just to confirm, is it still not working?

Hi again Ady,

Sorry, I've now discovered that it isn't working 100%. I have a forwarding rule in Gmail that forwards all my incoming mail to my tiscali address. It's those forwardings (only) that get rejected. If I forward manually it works. Here's an example today of the failure:

"The response from the remote server was:

550 5.7.1 Message rejected per sender's DMARC policy - OXSEU001_514 - https://postmaster-oxseu.vadesecure.com/inbound_error_codes/#_514"

Thanks for letting us know that your mail is working normally again.

Hi Ady,

Many thanks for your reply. In the meantime the problem, which applied only to messages from Gmail to tiscali - vice versa was OK - has gone away. I guess that TalkTalk changes its E-mail blocking policy on a daily basis. An explanation of what happened on this occasion would be helpful.

Hi GWEDWA, are you able to send mail if you send it from webmail direct to the gmail address?
