The digest is written to a special mailbox that you define. List users can choose between receiving a digest and receiving all messages as they are sent. To receive the digest, list users must send mail to the list server (imailsrv@your_IMail_server_hostname) and enter the following command in the body of the message:
set mode digest listname
where listname is the mailing list name. A confirmation message will be sent to the user.
To cancel digest mode, users can enter the following command in the body of the message:
set mode standard listname
where listname is the mailing list name.
