I don't know what Magnus meant here.

if this ISP supports extensions, you can forward to
dogs.cn+user=domainexample.com
so that a later server can get the original address from here. This
assumes you have some control at the other end.

if he doesn't support extensions (but you still have some control at the
other end), you can play with the "To" header (aka multi-drop
mailboxes). but this is uggly and fragile.

The best would be if he accepts relaying from your network to some
domains (whatever is the user part).

I meant that /test\.com/ matches any address that contains "test.com".
Including contest.company.com.

better use hash maps since you don't need pcre here.

relay_domains is just to declare which domains you accept to relay any
mail to.
if you don't need to open the port, just remove ":587" so that the
standard port is used.

but this assumes that the relay ISP accepts to relay any mail for you,
not just mail to "dogz".
