SV: SV: Looking for a guide to collect all e-mail from the ISP mail server

As I previously stated the reverse pointer does not have to match your domain. 

Suppose you ran a hosting company called host.com. Suppose you had clients client1.com and client2.com. This requires virtual mailboxes. That is one domain, host.com provides email services for client1.com and client2.com. Most servers would just have a reverse pointer to host.com.
