About public mail lists A mail list lets you broadcast messages directly into people’s Mailboxes where they are likely to notice them immediately. This way, you are sure users will get the message. For most regular communication and all two-way communication, conferences are a better solution since they decrease the number of messages in users’ Mailboxes and they require less maintenance. When you add users to your system, you have to remember to add them to the appropriate public mail lists. If you use conferences and Model Desktops, they will be added automatically. If a conference will meet your communication needs, use it instead. A mail list is an excellent solution for groups of users who do not have mail addresses on the local server and may only log in from time to time to view specific conferences. The mail list for these users would be made up mainly of Internet email addresses. For a business environment, a mail list is a good solution for resellers, since few of them have addresses on your local server and the mail list will consist mostly of Internet addresses. If you want to send all your resellers an important message and want to be sure they receive it quickly, send the message to the mail list. If you have regular product updates, can post this information to a resellers conference instead. For education environments, a mail list is a good solution for alumni, since few of them will have addresses on your local server.  Your mail list will consist mostly of Internet addresses. If you want to send all alumni an important message and want to be sure they receive it quickly, send the message to the mail list. If you have regular school updates, post this information to the website instead. Top For more information Adding and securing public mail lists
