question: i tried to add the alias_domain to mailman using Mailman Core REST APIs because I read about https://mailman.readthedocs.io/en/latest/src/mailman/docs/mta.html#unusual-p... ; entering the mailman console and doing dump_json('http://localhost:9001/3.0/domains/example.com/lists') was giving me error that dump_json is not an available module.

is that the way to go? should I add a an alias_domain to Mailman in order for it to output a postfix_vmap when doing mailman aliases? and then add it to postfix main.cf like so

virtual_alias_maps = hash:/etc/postfix/valias, regexp:/opt/mailman/var/data//postfix_vmap

I think the above should work for you. As far as dump_json is not an available module goes, the docs reference a lot of helper functions that are described at <https://mailman.readthedocs.io/en/latest/build/lib/mailman/docs/documentatio...>. These need to be imported. I.e., for dump_json

from mailman.testing.documentation import dump_json

But, if you are just trying to set an alias_domain for the domain and you have Postorius, you can do that via Postorius.

If not Postorius you can use mailman shell, For example

$ mailman shell
Welcome to the GNU Mailman shell

>>> dm = getUtility(IDomainManager)
>>> d = dm.get('example.com')
>>> d.alias_domain = 'x.example.com'
>>>

Then you need to do mailman aliases to create/update the maps.
