554 5.1.0 188.8.131.52 Comcast block for spam
Sending messages out and most of the recipients at Comcast are not getting their email. I receive the email bounce message with error message 554 5.1.0 184.108.40.206 Comcast block for spam
however the recipient does not have the spam filters set in their online mail service.
This all started just about a week ago probably around November 30th 2020
My email smtp server is not from comcast but I am using smtpout.secureserver.net - As far as I can see this is only happening to Comcast email recipients the others all receive the message, and before this last week all messages were going through to these same recipients and non of them have changed anything with their email or spam settings.
