Changes made to "Allow remote mail to local groups" take effect after
stopping, then restarting the IMail SMTP service. Did you restart it or
reboot the server recently?

IMail will allow the *creation* of group aliases regardless of the setting
mentioned above.

Local groups are groups that are local to your IMail server, i.e., that have
been created on your IMail server. Said local groups may include addresses
that are remote (not local users) but the group itself is local as it
resides on your IMail server.

Quoting from the very same KB article that you mentioned:

"When this option is enabled the SMTP server accepts mail addressed to a
local Group Alias. If not enabled, the SMTP server does not accept mail from
remote hosts to a Group Alias."
