We're moving a bunch of sites from one of our cPanel servers to another one. What i'm interested in is the best solution for making sure that mail accounts are not affected by propagation. The cpanel account transfer will transfer all mail from old->new but from the inital DNS change there is always a chance that some mail will be routed to the original server not the new server. Short of asking someone to check both mailboxes for a short time is there a more solid solution we can put in place? We tend to have full control of DNS so we can do what we want from that end if need be.
Let me know if this doesnt make sense.
