Notes
• Malicious senders may attempt to send traffic directly to port 25 on your
server, and bypass filtering and security. We recommend you configure your
email server or firewall to accept traffic only from the Message Security
service.
• When using a batch file, comments begin with a ‘#’ hash symbol. If not on a
separate line, the hash symbol could be interpreted as part of a user or
organization name.
WARNING: You must be sure to add all of your domains to the Message Security
service before locking down your firewall to accept only email traffic from the
service IP range. Otherwise, email sent to unregistered domains may bounce.
