Somehow I am thinking maybe you might be more interested in exploring a DISTRIBUTE job, where the target addresses are supplied with the message to be sent. I haven't actually done any of that so I cannot supply any actual guidance, but from what I have seen over the years I think maybe it might fit your scenario. In other words, instead of asking LISTSERV to say "oh wait, here is a posting for a list, let me go dig up a zillion subscribers" you would create some new application that will pull the list from your LDAP server and create the DISTRIBUTE job and mail it. Alternatively, you might explore using DBMS-hosted lists, and point LISTSERV to the database server that your LDAP server is using. I don't have details with that either, just sharing the wisdom accumulated from tracking THIS list for a few years now. >>> [log in to unmask] 4/12/2007 10:10:11 PM >>> At 9:49 PM -0400 4/12/07, Paul Russell wrote: >On 4/12/2007 15:41, Bill Verity wrote: >>Is it possible to manage subscribers through an exit?

Thanks Paul, hoped you would answer since I know you do a lot of this. But I want to build the list at the moment the mail is sent. What exit would I take? I don't see one for this time period. -- Police were called to a daycare where a three-year-old was resisting a rest.
