Can directadmin.conf options domainips_default_ip contain mulitple ip addresses?

Is it allowed to list mulitple IP addresses in the domainips_default_ip config?

Eg.

domainips_default_ip=;

This seems to work, but maybe I miss something?

Why?

I'f added an extra IP to my server (both IPv4 and IPv6) and I want to make sure exim only sends through one set of them.

I know there is the directadmin.conf option `domainips_default_ip` but I can't find any help on that option (it's not listed on https://help.directadmin.com/item.php?id=284 ).

What I've done and what seems to work is to just add both an IPv4 and IPv6 addres to the option

domainips_default_ip=;

So that after running

echo "action=rewrite&value=domainips" >> /usr/local/directadmin/data/task.queue

my /etc/virtual/domainips now contains:

*:;

Thanks !
