The comments are in some downstream package. They aren't in the default
GNU Mailman distribution.

If you go to the list's listinfo page, what does it say the list posting
address is? If it says listn...@example.com, then either you had
different settings when you created the list, or you changed the list's
host_name attribute on the General Options admin page from
myhost.example.com to example.com.

On the other hand, if the listinfo page says listn...@myhost.example.com
then all the email addresses Mailman generates for this list are
@myhost.example.com. Now they probably work because

>> POSTFIX_STYLE_VIRTUAL_DOMAINS = ['myhost.example.com']

says generate virtual alias maps for Postfix for any list that has
host_name myhost.example.com, so if Postfix is configured to use
Mailman's data/virtual-mailman, mail sent to list addresses
@myhost.example.com will be properly delivered.

Note that all DEFAULT_EMAIL_HOST does is set the default host_name
attribute for new lists. Once a list is created, it has no effect.
