HowTo: Integrate mailing lists with forums using Listhandler and Mailhandler
To allow users to post to and receive email from Drupal forums.
The Listhandler module allows you to connect mailing lists to forums and vice versa.
It works in conjunction with the Mailhandler module. Mailhandler receives an email and then asks Listhandler if the received email is part of a list. If the email is from a mailing list associated with a forum on your site then Listhandler adds the received email to the forum.
Additionally Listhandler will take every post to a forum and, as long as that forum is associated with a mailing list, post the message to it. Checks are made to ensure that a continuous cycle of emails and posts aren't generated.
Mailhandler and Listhandler can deal with attachments in emails and in forum posts.
The Listhandler administration page allows you to set an 'anonymous user' email address and configure the mailing list attributes.
