List Administration

List-server mailing lists or "automated" mailing lists, are used widely on the Internet as a means of sharing information about a topic. The IMail list server lets you set up list-server mailing lists that receive mail and resend mail to all the users on the mailing list.

The list server can also archive messages and send them periodically as a single message or "digest."

Domain: Shows the current selected domain. From the drop down you can pick any of the domains available to this administrative user account.

Search Box. Requires entering a minimum of two characters, and the search will automatically begin narrowing the mailing list names. The search assumes a wildcard automatically after the characters entered.

Caution: Search requires a minimum of two characters for the search to process to begin.

List Name. Click a list name to modify a list. Click or to sort the list.
List Owner. Assigned list owner.
List Administrator. Assigned List Administrator.

Add. Click Add to create a new list on IMail Server. For more information, see Adding an E-mail List.

Edit. Select and highlight a list, then click Edit to update an existing list. See General List Options.

Delete. Select a list that you want to delete from the List list, then click Delete to delete the list.

If the List Server has multiple pages, use the page navigation control which appears below the list names.

Default List Settings

List Owner's E-mail Address. Enter the full e-mail address of the list default list owner. This is the mail account that receives all messages (such as Subscribe and Unsubscribe requests) to the list. It is also the account from which help messages are sent and to which error messages are sent.
Note: The List Owner e-mail address does not have access to the List Administration pages unless the e-mail address is same as the local list administrator or has List Administrator permissions for the local domain. See the User Properties page.
Administrator's Local User ID. Enter the default list administrator user ID. Enter only a User ID (do not add the full e-mail address) that resides on the local domain for the list administrator. This will allow local list administration permissions for only the specified list.
Important: To allow permissions for all lists, the User ID can be given List Administrator rights See the User Properties page.

Note: The list administrator and list owner are usually the same person, but a "dummy" user account can be set up to be the list owner in order to hide the identity of the list administrator or to give the impression of more people being involved in the list management.
Maximum Message Size (bytes). Enter the maximum size of a message that can be sent to the list. Enter 0 if you want the size to be unlimited.
Number of Recipients Per Message. Enter the number of recipients each SMTP process will send to. To calculate this number, divide the expected number of subscribers by 25. The result is the number of recipients per message.

Note: We recommend that no more than 25 processes be used by a list.

Example:

You want to send an e-mail to a list of 5,000 subscribers. Divide 5,000 (number of subscribers) by 25 (number of processes) and the result is 200 (recipients per message). So you would have 25 processes that each handle 200 recipients.

If you increase this number, you may need to also increase the number of SMTP processes. For more information about how to change the default number of SMTP processes for IMail Server, see SMTP Settings Advanced Options.
