3.13.3 Bulletins

The bulletin feature allows you to send important announcements to all POP3 users without mailing them. It works by creating a bulletin source mailbox and sending the announcements to it.

After a user successfully authenticates, pop3d checks the last bulletin number the user receives. The bulletin number refers to the number of the bulletin message in the bulletin source mailbox. If the latter contains more messages, these are appended to the user mailbox.

The user last bulletin number can be kept in two places. First, it can be stored in file .popbull in his home directory. Secondly, if Mailutils is compiled with DBM support, the numbers can be kept in a DBM file, supplied via bulletin-db configuration statement. If both the database and the .popbull file are present, the data from the database take precedence.

To enable this feature, use the following configuration statements:

bulletin-source mbox

Set the URL of the bulletin source mailbox.

bulletin-db file

Set the name of the database file to keep last bulletin numbers in.

The following example instructs pop3d to look for the bulletin messages in MH folder /var/spool/bull/mbox and to keep the database of last delivered bulletin numbers in /var/spool/bull/numbers.db:

bulletin-source mh:/var/spool/bull/mbox;
bulletin-db /var/spool/bull/numbers.db;
