Using a List of Sender Addresses for Incoming Connection Rules

Mail flow policies allow you to use of an address list for certain settings that apply to a group of envelope
senders, such as rate limiting exemptions and mandatory TLS connections. An address list can consist
of email addresses, domains, partial domains, and IP addresses. You can use the Mail Policies > Address
Lists page in the GUI or the

addresslistconfig

command in the CLI to create an address list. The

Address Lists page displays all address lists on the appliance, along with any mail flow policies that use
an address list.
