You can place “comments” in the file. Lines that begin with a ‘#’ character are considered comments and 
are ignored by AsyncOS. For example:
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.
Procedure 
Step 1
Select Mail Policies > Address Lists.
Step 2
Click Add Address List
Step 3
Enter a name for the address list.
Step 4
Enter a description of the address list.
Step 5
(Optional) To enforce using full email addresses in the address list, select Allow only full Email 
Addresses
.
Step 6
Enter the addresses you want to include. You can use the following formats:
Full email address: 
user@example.com
Partial email address: 
user@
Note
If you have selected Allow only full Email Addresses, you cannot use partial email 
addresses.
IP address in their email address: 
@[1.2.3.4]
 
All users in a domain: 
@example.com
All users in a partial domain: 
@.example.com
Note that domains and IP addresses must start with a 
@
 character.
Separate email addresses with a comma. If you separate the addresses using a new line, AsyncOS 
automatically converts your entries into a comma-separate list.
