I can’t seem to receive emails from BT without them being blocked “ The response from the remote server was: 554 5.7.1 Your message was rejected due to bt.com's DMARC policy. See https://support.apple.com/en-us/HT204137 for info”

I can’t seem to receive emails from BT (my phone and internet provider) on my iPhone. They keep being blocked. I used to be able to click on “mime-attachment”

but this no longer works. I’m currently running 15.5 which continues to be unhelpful. There are other company’s email that also don’t work.

I get this sort of message:

“ The response from the remote server was: 554 5.7.1 Your message was rejected due to bt.com's DMARC policy. See Postmaster information for iCloud Mail - Apple Support for info”
