I have notifications of new blog set up as html style to go to registered users. 90 % of users have received the message but a number of members predominantly ntl /virgin media have not received the notice.
I have received the typical response
mx.tb.ukmail.iss.as9143.net Remote Server returned '<mx.tb.ukmail.iss.as9143.net #5.0.0 smtp; 554 5.2.0 GBHd1s01s196Phl01BHfYP Spam content found>'
It also appears that my admin email has become blocked by the same process and now some account holders can't get a direct email from my own admin email account.
Is there anything I can do to eliminate the problem. All users emails are registered as users with consent
