I realize that I have omitted an important point in my presentation of the network-wide 'List-ID' feature. By default, all lists are considered to be network-wide lists whose addresses ought to be communicated to other servers. Only confidential lists are "kept secret". You probably have a lot of local lists on your server which are of no interest to the network. For example, you might have a list of the people in the systems group, a list of all the teachers of this or that department, etc. You probably didn't consider these lists as being "confidential", and thus you didn't flag them as such. However, this means that they will be entered into GLOBLIST FILE and that people from everywhere in the world will try to signup to them. This will increase the size of the LIST GLOBAL command output and also the disk space required by GLOBLIST FILE. Thus you should change these lists to: Confidential= Service Service= Local This will have the side effect of not preventing them from showing up on the output of a "LIST" command if the sender is not in the service area. That is, your local users will not be affected, but remote users will not "see" the list and will consequently not try to subscribe to it. This change should be made before you install 1.5n, ie NOW :-) A new keyword will be introduced in release 1.5n: "Daily-Threshold", which will default to 50. It indicates the maximum number of acceptable mailings a day for the list; if more than this amount is received in any given day, the list will be placed in hold status and the owner will be notified. The "counter" will then be reset so that a "FREE" command will release the list and let in up to Daily-Threshold additional mailings. The list will remain held until manually released (ie it won't be reset at midnight). This should prevent loops from going on forever. If you are not satisfied with the default value, you should be sure to change it before installing release 1.5n. I have other new features to announce but I'll make it a different note to make database searches on the subject easier. Eric
