We pretty much do the same thing now -- create a list via web then run a makefile to create aliases.lsv, which then gets edited into /etc/aliases by a nightly cron job. The cron job also propogates an altered version of /etc/aliases around to some backup systems (we have two kinds of mailing lists: old-style sendmail aliases and Listserv lists. The sendmail lists are available even if the primary system goes down; the Listserv aliases entries on the backup systems are directed back to the single Listserv system, so they aren't as reliable). A CGI script could be written to run the makefile and edit the result into /etc/aliases, but it hasn't seemed urgent enough, I'm not sure about the security, and I'm worried about too much editing of /etc/aliases during primetime. Sometimes it's nice having a delay before the list goes "live". Eva Kalman [log in to unmask]
