And are there /etc/mailman/virtual-mailman.db and
/etc/mailman/aliases.db files created by Postfix's postmap and
postalias commands? The defaults for these are

POSTFIX_ALIAS_CMD = '/usr/sbin/postalias'
POSTFIX_MAP_CMD = '/usr/sbin/postmap'

and if those are correct, the list create process should run them
automatically after updating the virtual-mailman and aliases files.

If all your lists are in the realdomain.com domain as are the first
two, you aren't really using Postfix virtual domains for Mailman and I
think you could do without POSTFIX_STYLE_VIRTUAL_DOMAINS and
/etc/mailman/virtual-mailman, but I think it should work as you have
it if the *.db files have been updated.

Caveat - I'm far from a Postfix expert.
