ListManager can automatically deny subscription requests and postings from addresses you specify by using bans. ListManager's bans can be used as a permanent suppression list, to prevent those who have complained about being sent email from you from being added to a list or from receiving future list postings, or to pre-approve members.
Subscription requests from a banned address will be rejected, and administrators will not be able to add or import banned addresses.
Bans can be created for domains, user names, or complete email addresses. There is no "wildcarding" (e.g., "example.*"). If a domain is banned, subdomains are banned as well (e.g., "example.com" bans "host.example.com").
You may enter bans one by one, or import a list of bans. Bans can be created for individual lists, sites, or for the entire server.
Server administrators have the option of applying bans. When Apply Bans is clicked, all addresses marked as bans will appear as "unsubscribed" after the start of the next ban reload cycle (this task is set to disabled by default).
Applying bans can also be done automatically, as a server scheduled task.
There are three types of bans:
1. Always accept
2. Conditionally accept
3. Reject
Always Accept
"Always accept" bans prevent other addresses from joining. All other addresses will be rejected, unless there are "Always accept" or "Conditionally accept" bans for them. If you want to restrict membership to a particular domain, use "Always accept". Do not use "Always Accept" bans if you want other addresses to be able to join.
Once an address matches an "Always accept" ban, no further checks will be done on it. Therefore, an "Always accept" ban overcomes a "Reject" ban.
For example, if you have an "Always accept" rule for example.com, but a "Reject" rule for joe@example.com, joe@example.com will still be able to join. If you do not want joe@example.com to join, use "Conditionally accept" for example.com. Those who do not have an example.com address will not be able to join (e.g., aol.com, yahoo.com, hotmail.com, etc.).
Note that "Always accept" ban rules require a domain.
Conditionally Accept
"Conditionally accept" ban rules allow the conditionally accepted addresses to join, except those explicitly rejected with a "Reject" ban. All other addresses will be rejected, unless there are "Always accept" or "Conditionally accept" rules for them.
For example, if you have a "Conditionally accept" rule for example.com but a "Reject" rule for joe@example.com, everyone at example.com will be able to join except joe@example.com. Those who do not have an example.com address will not be able to join.
Note that "Conditionally accept" ban rules require a domain.
Reject
"Reject" bans the specified addresses from joining, except those with an "Always accept" rule. This is the most frequently used ban rule.
For example, if you have a "Reject" ban for the address mary@example.com, mary@example.com will be rejected; all other addresses will be able to join.
ISPs using multiple ListManager servers may choose to use one as a Global Ban Server. These bans will not appear in the local list of bans, but when apply bans is clicked or scheduled on the local ListManager server, it will also check for bans on the Global Ban Server as well.
The United States government has specified strict rules regulating sending email to domains used by wireless devices. ListManager may automatically download the list of wireless domains maintained by the FCC and ban those domains from receiving email. The URL for this list may be changed in Utilities: Administration: Server: Server Settings: Security: Bans.
NOTE: ListManager will NOT download this list of domains to ban unless theFCC Domains scheduled task is enabled. To have these domains banned, you must either Apply Bans in Members: Ban Addresses or enable the Apply Member Ban Rules scheduled task.
To view or edit a particular ban, click the user name or Edit. You will be taken to the Members: Ban Addresses: Edit Ban page.
You may change the order members are displayed by clicking on the up or down triangles on the column headings. The headings are:
Username
The user name associated with this ban (everything before the @ sign in the email address).

Applies To
Specifies whether this ban applies to a particular list, site, or the entire server.
Type
The type of ban: Always accept, Conditionally accept, or reject.
Created
The date and time this ban was created
Ban Options
