Overview of Incoming Mail Policies
Step 4
Define users for the policy.
You define whether the user is a sender or a recipient. (See
for more detail.) The form shown in
defaults to recipients for incoming mail policies and
to senders for outgoing mail policies.
Users for a given policy can be defined in the following ways:
–
Full email address:
user@example.com
–
Partial email address:
user@
–
All users in a domain:
@example.com
–
All users in a partial domain:
@.example.com
–
By matching an LDAP Query
Note
Entries for users are case-insensitive in both the GUI and CLI in AsyncOS. For example, if you
enter the recipient
enter the recipient
Joe@
for a user, a message sent to
joe@example.com
will match.
If you store user information within LDAP directories in your network infrastructure — for
example, in Microsoft Active Directory, SunONE Directory Server (formerly known as “iPlanet
Directory Server”), or Open LDAP directories — you can configure the appliance to query your
LDAP servers for the purposes of accepting recipient addresses, rerouting messages to alternate
addresses and/or mail hosts, masquerading headers, and determining if messages have recipients or
senders from specific groups.

If you have configured the appliance to do so, you can use the configured queries to define users for
