A couple of possibilities. Both options assume that the DNS server for the school's domain is external to the box itself. 1. If the box will be down less than four hours, just shut it off. Servers sending you mail will just not be able to contact the school's mail server, and will retry later. If it'll be down longer than four hours, most sendmails will send a warning back to the sender of the message, undoubtedly confusing some of them, but it'll still work. 2. If you have access to the DNS server for the school and the TTL for the MX record is short enough for the change to propagate in time, set up a secondary MX record for the school pointing to Box 2. Then on Box 2 I think you just need to add the school's domain to control/rcpthosts, but not to control/locals and it will queue the mail until the primary MX comes back on line. (Disclaimer: I've never set up a secondary MX box using qmail, but I believe this is how you'd do it.) Hope this helps.
