This is not correct. You do not need to add sites on the RAQ to the relay hosts/domains.
This is for RELAYING, which means sending something on which did not originate from the
server. I send mail all the time through the server and my domain/host is not in the
relay from....

Relay from is for IPs or Domains from which you WILL RELAY. If your hosting customer has
a static IP, it is recommend that you use the IP, since the domain allows an entire
domain of users, presumably an ISP in this case, to RELAY (i.e. SPAM) through your box.
Be very careful about adding a the domain of an ISP.
