After the up’s and down’s of the email service, I have taken the decision to continue to use the web-hosting that you are good at and move the email to another host.
Sorry, I was loosing too many vital mails.
I now seem to have a problem that emails from a particular provider “One” do not get through, others do.
My MX record is correct and has propagated throughout the world in all but a few servers (mail-02.dd24.net). The One provider has suggested it is on the Infinity Free side and that the email routing is being blocked. I am quite skeptical about this explanation, however, since it looks like mailboxes were restored from a backup recently perhaps a whitelist has not been restored fully somewhere in the Infinity system.
I have included the failed transcription below.
Your thoughts please.
Many thanks in advance
