* Both moderated and closed lists have a limit of 40,000 characters per message, to keep list messages under control. A message that is too long will be bounced to the moderator (you) for approval. If you approve, it can still go through. If you want to change the limit, you can get the config file, edit it, and put it back in place.

This problem is solved by installing a mailing list on the WPI email hub. Being on the mail hub, not in an individual's mail setup, the mailing list is available to anyone on the Internet. We call this a system mailing list. The hub deals with this mailing list the same way, irrespective of the personal mail program that someone might be using.

This web form is designed to let people manage system mailing lists of the form listname@WPI.EDU

• A system mailing list resides on the campus email hub, smtp.WPI.EDU. This means that people other than you can mail to the list, since it is centralized, not in your personal address book.
• Mail sent to the mailing list will only show the list name in the To: line in the headers; it will not list the individual recipients' addresses.
• There are three forms of mailing list.
  1. An open mailing list, by which anyone on the Internet could mail to the list unimpeded.
  2. A moderated mailing list, in which you control the mailings to the list. You will be assigned a approval word which must be used to mail to the list, even in messages authored by you, and by which you could approve mailings to the list which were authored by others. This enables you to protect the list recipients from off topic discussions, spam, cascades, or other mailing list abuses. *
  3. A closed list is like a moderated list, in that it uses the same mailing software. However, it works by only allowing list members to mail to the list. This is something of a control on mail to the list, without requiring moderation of each message sent to the list. *
     
     Note that the complete email address of the sender has to be in the list, or the mail will be rejected. e.g. the email address of login xyz at wpi should be written xyz@wpi.edu in the list of addresses, or else the software will deny delivery of mail from xyz to the list.
