This plugin allows you to prefix the subject line of list messages of all lists with the list name.
Seven standard formats are available setting the appearance of the list name prefix in the subject line of messages. There is an option for setting the list name to upper case in the prefix. There is a further option for defining a custom format.
The standard formats are as follows:
The custom format selection (appearing as format 8.) allows you to enter the 'Left Bracket', that is, the characters to appear before the list name in the prefix. The Left Bracket may be empty. You can also enter the Right Bracket/Separator. These are the characters appearing between the list name and the subject proper.
