Gateway and open relay

Gateway
1

Hi.

I'm a little confused on this: with Djigzo setup as a gateway in my DMZ,
won't it look like an open relay? What keeps a service like Spamhaus.org
from identifying it as an open relay and blacklisting my IP? How is this
prevented?

Thanks in advance.

Only the IP addresses added to "My networks" are allowed to relay email
to external users. You therefore have to make sure that only the IP
addresses that are under your control are approved (for example only
approve internal IP addresses if you use NAT). External IP addresses
which are not approved (i.e., which are not added to "My networks") can
only send email to the relay domains (i.e., the domains for which the
server handles email, aka, your internal domains).

Kind regards,
