[serverhenry]

Hi all,

Really need help here.I just finish develop a website to my client.But here the problem.My client want to keep their email with current hosting with old vendor becoz they already paid them for email hosting...and i just host new website that i develop website in my hosting.

My question...how i can do it or what i need to tell to old vendor to do....so the domain for website pointing to my hosting...and email remain with them

I already ask them to do what they need to do...but i think the domain for the website still pointing to them...but they insist they already pointng to my hosting

how i can know the domain already pointing to me or still pointing pointing to their hosting?what proof i need to ask them that they already update the domain pointing to me?

Reallly appreciate any help, thanks!
