My TalkTalk email failure to receive emails from many sources, circa 17:00-05:00, 12/12/24-13/12/24, which prevented some 2 stage verifications as did not receive the verification codes. This included the login to this community and the Dell login,

I sent some test emails to my TalkTalk mailbox (from Plusnet, gmail, etc) which were not received. I received no messages to indicate that the emails had been blocked but initiated the "Delivery Status Notification" in Thunderbird and got the following and similar responses:
- These recipients of your message have been processed by the mail server:
xxxxxxxx@homecall.co.uk; Failed; 5.3.0 (other or undefined mail system status)
Remote MTA mx003.tt.xion.oxcs.net: network error
- SMTP protocol diagnostic: 550 5.7.1 Message rejected per sender's SPF policy - OXSEU001_514 - https://postmaster-oxseu.vadesecure.com/inbound_error_codes/
Shortly after 05:00 I tried the Dell login again, which failed at my first attempt, but was then successful. The mailbox appears to be working now but I fear that some emails may continue to be blocked and that a recurrence of the issue may occur.
Please raise a ticket on this issue
