I neither understand where the IP address comes from nor why the
address was added there.

An IP address range for dc_relay_nets makes the host a smarthost for
this IP address range. That is, it will relay _any_ message coming in
from this IP address range.

A correctly configured host will accept incoming mail for its local
domains from any IP address. This is the intended behavior for an MX
server. A message coming in from a lesser priority MX will be
accepted. It is just a normal incoming message.

A host configured to be secondary MX (this is not the case for the
OP's machine) needs to have the domains it should MX for in
dc_relay_domains, causing it to accept mail for these domains from
arbitrary IP addresses and to continue to relay the message according
to the MX records from public DNS.

I suspect that the change from "not working" to "working" is unrelated
to your suggested change.
