What is the fastest and cleanest way to deliver a notice to all users? Thinking in terms of campus emergency. The Cyrus MOTD function is a one-liner, and only works for IMAP clients. My first thought was to create a message 0. and then hard-link it into all user inboxes and reconstruct. I checked the code though and it seems only messages 1. and higher are recognized. Scratch that idea as we would run into collision avoidance problems using regular numbers. We have 2 Cyrus mail-stores about 30K users each. I assume there is some practical limit to recipients, or can I just list all users and send a single message to the entire list at one shot? ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
