BT email refuses to send due to "policy issues"

[hanschristian1]

I am unable to send emails this morning, each email (except one sent to BT phishing) not sent due to "policy issues" relating to the alleged content of my emails. Even empty emails are refused. What causes this?

Hi @hanschristian1 thanks for posting, I'm sorry to see you're having issues sending emails. It normally means the spam filters have been triggered by something within the email but if blank emails aren't sending it may be something else like a block listed IP address.  Is this happening when you're connected to one internet connection in particular?

Thanks

Neil
