About 50 hours ago I set the domains DNS servers to point to the new hosting, and I realise it takes time to propagate through the net.
The old hosted site has an alternate domain pointed at it, as we want to keep it accessible till the new site is 100%, the alternate domain wasn't known to the customers.
But the weird problem i am having is that, emails to the site for the shifted domain (the one that is pointing to the new hosting), some are going to the old hosting, and before you say it, yes i know it is to be expected whilst the DNS change is propagated out.
However I have been communicating with the customer via email, and 90% of my emails are going to the new server, but the odd one goes to the old server, and thats whats confusing me 10 emails will go to the new server then suddenly one won't arrive and we check the old server and there it is, all by its lonesome in the inbox.
and also emails to the client from her customers some seem to go to the new server while others go to the old server and these customers can be using the same ISP
is this normal and will decrease over time.
anything i should be doing?
