Users are forced to use port 587 and authenticate. Rules on firewall only allow access to port 25 on my Imail server from known IP address such as client firewalls or servers that have processes that send email notices out. > If there would be a way to configure Imails SMTP-port to accept ONLY > SMTP-Authenticated connections (beside the messages comming from your new > gateway) this would be a solution for many of us even if it would still > not prevent attacks from the own users. On Imail 8.1 + you can force authentication on port 587. John T eServices For You "Seek, and ye shall find!"
