This issue should have nothing to do with the settings of

The list has been created and the data/aliases and, if the host is in
POSTFIX_STYLE_VIRTUAL_DOMAINS, the data/virtual-mailman files have
been updated, and now the Postfix MTA module is calling
/usr/sbin/postalias to update the data/aliases.db file, and the
postalias command fails.

Assuming /usr/sbin/postalias is the correct path (if not, set it in
mm_cfg.py with POSTFIX_ALIAS_CMD), this is almost certainly an
ownership/permissions issue.

Permissions should be at least 0660 on both the aliases and aliases.db
files and the owner:group should be the mailman user:group. In older
versions, bin/check_perms doesn't check all this.
