Ok here is the situation , think ive got it sussed but just wanted to run it past you guys:-

Client has domain and hosting with 123 , I will be hosting his site, but he has an exchange server that picks up his mail , there is a DNS record on 123 for it. So if I point the nameservers at EUK then change the DNS in WHM for his domain to point back to his IP will this work as it is at the moment ?

If it does work , will there be any e-mail downtime ? what would happen to the mail ?

Thanks.
