Don�t know if this is the right board to post this but it concerns email delivery failure to btopenworld.co and btinternet.com email addresses.
I am a Neighbourhood co-ordinator for the road where I live and have been forwarding emails to my members for several years without problems until today. Three of my members have email addresses with btopenworld.co and btinternet.com and today I received a delivery failure to these addresses from the postmaster at btinternet with the Diagnostic-Code: smtp;554 Message rejected for policy reasons (3.2.2.1)!
Does anyone have any information what this diagnostic code means?
