Our domain is wiseman.co.uk 220.127.116.11
I had many of my users complain that they are not receiving emails.
So I sent myself a message from yahoo.co.uk
and the reply I got was below...
Our ISP consultant type person is saying it because yahoo.co.uk is on a black list....and we should send him a list of emails address we want to come into our system so he can add them onto his white list...but I have 100 users with loads of potential client emails address...I don't think this is right...surely every possible address doesn't have to be added to a whire list does it ?
Is there a way to check where the mail is getting block and why ?
